BG looks like a stock photo with a purple brush painted over it, there really isn't any blending to it, even a smudge, a little brush work, and a couple blending layers would of drastically improved this image. The lighting is really off on the render, he has light all over him but the light source in the BG fades off and is directed in one position not directly onto it and the text is hard to make out.

I might be wrong about the BG being a stock, but that's what it looks like.
