For my anatomy class, we had a project where we had to fuse human and animal anatomy. I chose to blend the human torso, particularly the shoulder girdle, with the anatomy of a fox. I'm still working on it a little, but it's slow-going. I've always liked working with gouache, but it's hard to keep the look that I want.
I'll eventually scan the final, this is the nearly finished piece. You might notice the weird corners, I'm in the process of singing the edges to effect the paper to make it look old. It's still a work in progress. :)
