Chameleons Imitating Octopus

Inspired by some of the favorite animals of a good friend of mine.  Still working on it – just need to shade it and go over it with texture brushes.  Think I’m going to darken it up a lot and give it some depth, a little bit of grit… I might add a “real” octopus, off to the side looking confused or something.

New color scheme & title:  Decided on a simpler but more aesthetic (well, I think so anyway) color scheme.
