Step 2. Now that you have the cross section established, the next thing you will do is divide the head into thirds. This is the golden division you will use to lay all of the feature elements of the skull upon, i.e., the eyes, nose lips, ears, and so on. The primary, or stock look for the average human is even divisions between these thirds. But once understood, these divisions will be your guide to drawing charactures, character types for stories, or whatever. These divisions are as important as the golden cross section that began all this. The upper third is what you start with. This establishes the divisional units of the skull, i.e. it creates the volume to which the other 2/3rds will be measured. The upper 1/3rd is from the hairline to the brow line.
