I love it. GREAT feel and flow to it. Good lighting. When you apply the image and sharpen it, I would definitely make a layer mask and mask out parts (mainly the area around his left arm). Good effect on the text with the overlay. Not really feeling the duplicated render to the side, but it doesn't detract a ton from the sig. Maybe a bit larger on the text, but that's certainly not a necessary thing. Good lighting, good coloring, all around good sig. Probably your best I have seen.
Oh, and please get him underneath that inner border.
Pet peeve of mine you might say.
