1, determine the head type. The hypotenuse head is a shape with both positive and positive features. One side is more like the front, and the other side is more like the front. Please imagine the three-dimensional structure of this shape by combining the front and front pictures.
2. Draw a crosshair in the direction of nasal midline and horizontal midline. Note that the two lines are curved, and you must draw a three-dimensional effect. 3. Eyebrow frame. Similarly, the left and right sides are asymmetrical, and the downward line should also be bent. The side near it must be longer, depending on the angle of the head.
4, line of sight and ears, cheek line, ear line. The line of sight is similar to otolaryngology and horizontal midline; The cheek line is similar to the forehead and extends from the vertical line of the eyebrow eye frame. The plane formed by this line and the facial contour line on the other side of the nasal midline is the frontal face; The position of the ear midline is inferred from the position of the cheek line and the back line.
