Steve and I went through many iterations before we settled on a design for our caveman. Here are a few of the major changes. Most of the nice drawings are by Steve. All the painting is by me. You can see how I improved. Steve, did, too.
Too much like Fred Flintstone.
Chin too large. Also, it looks like a beard. Not appealing enough.
Too wide. Arms too big. Too innocent looking.
Too realistic and sausagey.
