People's faces vary widely. Many people's faces cannot be simply applied to these faces. Too many people's faces are a combination of two or three faces, and simply applying eyebrows may not be able to modify their faces. This paper introduces three steps to determine the eyebrow shape: according to the aspect ratio of the face, determine whether the eyebrow is flat or raised. If you want to lengthen your face, you can draw your eyebrows a little; If you have a long face, you can draw your eyebrows flat. Determine the position of eyebrow peak according to the inner contour. Determine the radian of eyebrow peak according to the straight curve of face. Mainly look at the cheekbones and mandibles, and consider drawing the eyebrow peak steeper or flatter. Following the principle of "broken square, broken circle and broken square", there are many facial curves, and the eyebrow shape can add some sense of angularity and outline; If the face is already contoured, the eyebrows can be smoother. As long as you follow the three elements, you can determine whether the eyebrows are drawn flat or picked. If the position and radian of the eyebrow peak are determined, the eyebrow shape can be determined. How to find the eyebrow shape that suits you? Determine the aspect ratio of the face. If the aspect ratio of the face is close to 1:0.6 18, which belongs to the standard ratio, a standard eyebrow shape can be drawn; If the face length is too long, such as 1. 2:0.6 18, the eyebrows should be drawn straight to adjust the width of the face. If the aspect ratio of the face is relatively wide, such as 1:0.8, the eyebrows should be radian, and some should be selected, but the beautiful radian should be suitable for the upper atrium position of the face.
