It is suggested to draw a plaster statue first. When drawing a plaster statue, because the mouth and nose of the plaster statue are relatively standard, it will be easier to draw a plaster statue's mouth and nose first, understand its actual shape, and then draw a person's mouth and nose. The drawing method of figure sketch nose is located on the central axis of the five senses and is the most prominent part of the face. The nose consists of three parts: (1) the bridge of the nose composed of nasal bones and cartilage; (2) The oval nose ball and the nasal septum below it; (3) The two alars are inclined outwards and downwards, and the nostrils are hollow. The whole nose is like a trapezoid with a narrow top and a wide bottom. It is necessary to sketch the nose carefully in the performance. The nose is located on the central axis of the five senses and is the most prominent part of the face. The nose consists of three parts: (1) the bridge of the nose composed of nasal bones and cartilage; (2) The oval nose ball and the nasal septum below it; (3) The two alars are inclined outwards and downwards, and the nostrils are hollow. The whole nose is like a trapezoid with a narrow top and a wide bottom. In the performance, we should carefully change its four parts. 1) nasal floor. This part is actually the bottom of the nose. Because it is physically more violent than other parts of the nose after receiving light, we are used to treating it as a special part to deal with punishment. The physical feature of this part is a grand layout composed of the transition surface of the tip of the nose and two nostrils. The transition above 90 makes the whole nasal floor in darkness, forming an obvious dividing line between light and shade. Two irregular nostrils create a huge reflection around it. These reflections and the boundary between light and shade are the difficulties in the performance of the nose. Be careful when depicting its rich light and shade, true and false changes. (2) the nose part. It is completely composed of nasal cartilage, which is divided into two parts: the tip of the nose and the alar. The tip of the nose looks like a sphere, and its two wings look like hemispheres, so it is obviously different from the trapezoid of the bridge of the nose in physical characteristics. This part is the highest point of the portrait face, which is far from the eyes. We can take it as the second focus of the face and hold a detailed description. (3) the bridge of the nose. This part is composed of the lower end of the nasal bone and two nasal cartilages, located in the middle of the nose, similar to a standard trapezoid, with a positive side and three obvious planes. When describing this part, we should pay attention to the shape and layout changes of three planes, as well as the sense of mass of the whole trapezoid and the embedding mode of its adjacent parts. (3)(4) nasal root. This part consists entirely of nasal bones. Near the double-tear mound, the upper end is connected with the downward curvature of the frontal bone. The nasal root is the narrowest part of the nose and the most urgent part of migration and transformation. Its contact with the eyes is also very sudden. So this part of the analogy changes a lot. But because it is too close to the eyes, don't exaggerate its changes when painting, so as not to weaken the performance of the eyes. Usually, it just exaggerates the analogy relationship close to the center of eye layout. The nose is the largest part of the face, which makes the face have strong light and shade changes. The ability to depict this part is flexible, which can exaggerate the role of light and shade and the role of layout: it can strengthen punishment and weaken punishment. The shape of the nose varies from person to person, and it is a tense part of the physical characteristics of the characters. When expressing, we should first grasp the general characteristics of its group, and then make some descriptions.
