Draw a large circle one-third of the way down your page if you plan to incorporate a body later. If you are drawing only an anime head, then place the head directly in the center of the page.
Dissect your circle with two horizontal lines to make three equal sections, then dissect the head in half vertically with one line. These lines should be light enough to be easily erased, but should still be visible.
Make a short, horizontal line directly below the circle of the head the same height as the last third of the circle. This will be the mark for the chin. Connect this line to the bottom of the circle with a faint vertical line made with a ruler.
Draw two diagonal guidelines. They should be tangent to the sides of the circle (next to, but not crossing), and intersect at the edges of the chin mark.
Expand the lower section of the face (the cheeks and jowls) by adding a half-moon shape (mirrored on the appropriate side) to each side of the head. Each section should span from just below the bottommost horizontal guideline to the outside of the chin line.
Erase your guidelines and fill in where you want your facial features to go.
