First off, love the effects and the text. They look absolutely sick. Second, that lighting is mind-boggling. His face looks professionally lit which I have my doubt that it actually was. My main concern is the blending of those two things together. Basically, the light is hitting his face on the right side of the sig. However the light sources I can distinguish are all on the left. Lighting on text like that looks amazing, don't get me wrong, but it should affect the render a bit more. If the render was on the left and the text on the right I think this problem would mostly be gone. I also wonder if a bit more could have been done with the BG. Kinda looks like 1 stock + 1 effect. It works, I just think it could work a little bit better.
