Here is my entry for the SCBWI draw this competition. There is some great work out there already for this new challenge.
I pen and ink with some Illustrator and Photoshop to make the final product. Below are some stops along the path.
Thanks to fellow SCBWI members Annina and Stephen for some suggestions.

Fascinating article in National Geographic about the origins of art and the first people that were its’ creators.
What I find most amazing, is that this art is as close to permanent as we are capable. In our current world, most of the art we create is fleeting, unable to survive only a few decades, but we are looking at art from the dawn of mankind.
