This was a concept for the arm of the Clockwork dragon project I was (and still am) working on. I was looking thru anatomy books to get this sort of muscle-y look to it. I still would like to complete this one, if only to cover it up with other things to make it a little more interesting. I was just trying to make the arm look like it worked, semi-organically. :3 We'll see if I get good enough to make this some time soon :3
