The Wookie is great. And I think the Vizago on the Joe Colton figure works really well. But the Cthulhu on the Kraus body is the winner for me. It really come together well.
I also like you attitude about the images being stolen. I've had artwork stolen before and I'm usually more upset that they used a crappy low res version than the actually theft itself. I read some stuff from Dave Sime who created Cerebus the Aardvark, that he doesn't really care if people rip off his art, if someone can do his characters better than he does, they deserve what ever they make off of it. It's the philosophy I've adopted.
