Proportion
- Good proportion is the most important starting point for this drawing. One way to achieve this is to begin with a circle in the upper middle of the drawing paper. The diameter should be equal to the width of the skull. Draw a vertical and horizontal line (cross-hairs) through the center of the circle. The next task is to draw the jaw by drawing a rectangle. Extend the rectangle down from the center line of the circle to a length equal to the diameter of the circle. It should be less wide than the diameter of the circle. If the diameter is 5 inches, then make the rectangle 4 inches wide, for example. The circle and rectangle give you the main proportions for the skull.
