This is the initial sketch from my Moleskine. It started as just a drawing of the chimp and just sort of took off from there.
This is a detail of the final drawing. It was done on bristol board with pencil and pen.
The stone tablet part finally finished.
This is a view of just the chimp with the rays of light. They worked well with a dark background, but didn't show up very strongly in the final piece. So I threw this in just for fun!
