I'm lovin' background to it. Maybe it would be cooler if you made half the signature dark and the other lighter since he is half and half. Just a thought. Nice signature tho!
Thanks guys, but if I made it dark on the right it would throw off the focal, and the reason its large is cause the size of the render I used, it wouldn't work if I had made it much smaller.
The background doesn't suit the render at all. He would look better on a dark background so his bright orange effects would stand out more. The white stuff to his left is weird and not very aesthetic. The background is actually sort of ugly, because of the brown colors, especially on the left...I would just fool around with the burn and dodge tools for this one, especially the burn tool. Try burning to background to make it darker, and I'd try to get some orange effects that match the render in there somewhere.
