it looks like it has a few perspective issues, i don't like the leftmost (of him) part of the sunglasses, they break perspective, i think you should make that part smaller than the right one.
anyway, it rocks! ^^
Sunglasses better now?
I think they should be more horizontal..
Edit:
chaged the sunglasses again.. (number 2)
I removed one stripe of the image, I am now working on another computer and I cant copy an image from here to paint, so I had token a screenshot, but now there is missing a small part.. ill fix that later..
