This is a fairly old pencil drawing I did for fun back in college, think it was in 2006 or so. It's one of the sketches that I still admire, even if it's not a recent one! :3
I was much more into animal anatomy in my college days, and while experimenting with drawing the skeleton of a buck, I ended up drawing the outline of the it's body around it, I think to help confirm whether or not the bones were in the right place.
