How to draw head

This is simple scheme how to draw a head in various positions. It's a Disney's method, and it's easy to understand. By the way I recommend to use a model. You can make it from any polymer clay, or take an egg and ping-pong ball and draw on them 'equator' and 'meridian' for see how the face comes under influence of point of view. ^_^
