1. Fixed component
The up and down position determines the size of the head. Draw the composition upwards as far as possible, and in principle, it cannot exceed the original size; Look at the direction of the face first in the left and right positions, and stay in front of the nose. Observe the basic proportion, whether a person's face is thin or fat, never be careless.
Looking for three stops
First of all, pay attention to people's basic dynamics. Under normal circumstances, the position of the eyes is not horizontal, but a little inclined. Secondly, it depends on whether the whole head looks up or down. Generally, there are not many opportunities to look up. When you look up, your eyes are generally in the upper and lower parts of your head. Your eyes look up high and your eyes look down low. After determining the position of eyes, find out the position of eyebrow arch and nasal floor.
Find the position of the nose on the face
On the basis of determining the three stops, first look at the distance from the outside of the nasal root to the face, and then find the width of the nasal root. Come down and find two alar positions. Show a large nose with relaxed lines.
4. The range of eyeball
Pay attention to the range of the eyeball. Don't look for the specific shape of eyelids too early. After finding up, down, left and right, look for the feeling of a sphere and express the dark side.
5. the range of the mouth
The most prominent position of the lower lip is from the bottom of the nose to half of the chin, and the mouth crack is slightly higher; After determining the height of oral fissure, the total thickness of upper lip and the thickness of lower lip quadratus muscle were calculated. Then set the corners of your mouth. The volume of the mouth should find the range of the orbicularis oris muscles on both sides, and people are the most advanced position. Don't look for lip lines, focus on the volume of your mouth. Roughly spread the whole dark side.
6. The outline of the ear, the outline of the face.
First of all, according to the position outside the corner of the eye, look at the distance from the sideburns to the corner of the eye and find out the width of the sideburns: look at your angle. If you can see the sideburns on both sides, you must draw them together, and the height should be consistent with the direction of the eyes; If you can only see one sideburns, pay more attention to the distance from sideburns to ears. Look at the height of the ear first, then look at the width, and set a big outline.
7. Head contour
According to the position of sideburns and ears, find out the outline of hairline and hair. Be careful not to hook the hairline too hard and relax. If you can't see the hair on one side of the forehead contour, you must pay attention to the thickness of the eyebrow arch and the position where the frontal tubercle turns.
8. Facial contour
The position behind the ear, according to the position of the sideburns, generally has two situations: when you can only see one ear, the cheekbone in front of your face is the most prominent place, so you should pay attention to inserting it downward in two positions (when you bite the muscle, you can see that the masseter muscle is below the cheekbone, and when you can't see the masseter muscle, the orbicularis oris muscle is in front of the cheekbone; The mandible is in front of the masseter or orbicularis oris muscle). When looking for the contour of the ear side, pay attention to the following points: the ear is slightly inclined, and the relationship between the ear and the mandibular end should be clearly seen; The turning point behind the mandible is as high as the corner of the mouth; Don't hook your chin with a single line, be sure to see the thickness of your chin and the distance from your neck. It is convenient to determine the position of neck and collar line.
Second, find a big structure.
1. Forehead structure
The frontal range of the forehead, from the vertical upward position between the eyes to the backward position of the frontal tubercle, is the frontal part; The part above the cheekbone and behind the eyebrow arch from the temporal line to the back is the part on the side of the forehead; The range between the side and the front is the range of the inclined plane.
2. The structure of the face
The forehead range is the facial forehead range from the zygomatic forehead range directly below the corner of the eye plus the mouth forehead range (both sides of the nose) and chin forehead range; The side of the face is the range of the side of the cheekbone plus the side of the masseter muscle, and the range between the side and the front is the range of the inclined plane.
3. The structure of the neck
The neck is the Adam's apple and the sternocleidomastoid muscles on both sides. The big feeling is a cylinder. Generally speaking, most of the back is covered by the collar, so we just need to pay attention to the structure of the Adam's apple on the basis of the large cylinder.
4. Hair structure
The most basic feeling of hair structure is to blend with the head, with the turning point of forehead curl; Secondly, the hair has thickness; Long hair should be grouped by hairstyle.
Third, analyze the structure of the five senses.
In this step, it is very important to adjust the shape. At the same time, check the problems in the initial shape setting and correct them in time.
1. Eyebrow arch and eyes
The eye is a sphere, buckled in the eyebrow arch. First, find out the range of inward folding of the eyebrow arch around the eyeball, focusing on the position of the nasal root. The eyebrows on both sides are unified and should be drawn together.
For the specific shape of the eyes, first find the highest point of the upper eyelid, then set two corners of the eyes and connect them (pay attention to the thickness of the eyelids, don't use a single line). The method of the lower eyelid is the same (note that the upper eyelid wraps the lower eyelid). The two dark circles should be in the same direction (note that the upper part of the dark circles is covered by one third of the upper eyelid), and at the same time, look at the specific characteristics of the eyelids and draw the volume of the eyelids.
2. Nose
On the basis of the scope of nose, first find the feeling that nose is close to a sphere, and we will shape it according to the sphere. Press your whole face under your nose and find the shape of your two nostrils. Pay attention to the same direction as your eyes. The arc of the outer edge of the alar on both sides is connected to the middle, and the range of the whole nose basically accounts for half of the nose root to the bottom of the nose. When drawing the bridge of the nose, first of all, pay attention to the position of the root of the bridge of the nose (where the middle lines of the two eyes are connected). The volume of the bridge of the nose should be understood as a cylinder, and the five tones should be complete (the highlight direction should be consistent with the nose)
Step 3: mouth
Draw the mouth first and find the middle position of the mouth according to the direction of the person. So that the direction of the mouth will not be a problem. Find out the position of the corners of the mouth, and be careful not to dig the lip line too hard. The ends of the upper lip should be hidden in the corners of the mouth at last.
Pay attention to the volume of the lower lip, and don't pick the lip line. First, the volume of the lower lip quadratus muscle turns up and down; The second is the turning point from left to right, followed by the drawing of the intersection line of the whole head (generally there are two turning points: one is the person, and the other is the position where the turning point below the cheekbone connects with the midpoint of the lower lip). The outermost part of the oral volume terminates outside the orbicularis oris muscle.
4. Ears
The shape of the ear is generally oblique. Pay attention to the front below. The key point of the roll is to grasp the prominent position of the upper helix and the lower lobe, and the middle is concave. Also pay attention to the thickness of the spiral line, and don't draw it into thin slices.
Fourth, adjust the order of black, white and gray.
The basic black, white and gray relationship of human head portrait should grasp the following points:
1. The five senses should be prominent.
The general order of heavy color on eyes: the overlapping position of upper eyelid and black eyeball is the first, the pupil is the second, the corner of the eye on the bright side is the third, and the corner of the eye on the dark side is the fourth; The whole upper eyelid is heavier than the lower eyelid; Grasp the volume of the lower eyelid, including all projections, and aggravate it. The approximate order of the color of the eyebrow arch is: the position of turning down to the light side is aggravated, and the turning position between the inside of the nose root and the eyeball is aggravated, which strengthens the projection of the eyebrow arch to the eyes; The eyebrows are finally drawn on the eyebrow arch, and the features are grasped. The general order of heavy nose color: the bright sides of the two nostrils are heavier, and the edges of the nostrils and nose are the heaviest; Strengthen the dark side of the nasal floor and strengthen the boundary line; Strengthen the nose. The approximate order of heavy mouth color: the middle of the mouth crack is the heaviest, followed by the bright corner of the mouth and the dark corner of the mouth; The most important thing is the heaviest oral fissure, followed by the lower lip and the turning point of the lower lip, followed by the lower edge of the lower lip.
2. Black, white and gray faces
Grasp the big boundary line of the whole face, but the color must be weakened, otherwise it will eat the color of the five senses. Shape according to the three directions we divided at the beginning, and the volume will be fine. Emphasis is placed on several heavy colors above the outline of the face. The heaviest color is the chin, the outline of the bright chin is the heaviest, and the dark side is the weight between the chin and the neck. Other contour sequence: the upward position is weak, and the downward position is heavy. The chin and neck give the impression that the chin is in sharp contrast and the neck is gray (so that the neck can retreat).
3. Black, white and gray hair
When drawing hairline, try to give the line in the direction of growth. We grasp the principle that the intersection of big hair is consistent with the face, and draw the thickness and characteristics of hair. The heaviest color is generally outside the bright forehead, followed by dark hair and the outline behind the ears, and the third is the intersection.
4. Black and white ash around the neck
Mainly highlight the dark side outside the collar on the bright side to grasp the projection relationship on the dark side. The front of the projection is heavy, and everything else is gray.
Five, unified contrast, complete the picture.
Adjust the disharmony of the picture and depict some small details, such as obvious wrinkles and so on. Adjust the connection position of each part to complete the picture.
