Basil Wolverton study

I've never did an study from this guy. It's pretty scary for the first time, it's so great.
First, the verbal analysis:
-BIG head
-BIG Teeth
-Little face
-Little body
-Long hair vertical, which breaks the monotony with the horizontal teeth.

this first step always came out pretty stiff. Im doing it with some fear.
-The head was too little, so the body.
- the upper part of the cranium, where the upper lip begins, it's smaller.

Level1_2:
