I like the texture over this, but the lighting and text are poor. Its also very plain. If you need help coming up with some ideas, go to the GFX Resources and download some psd's.
the lighting is too strong on him and it needs some more to it, looks like just the picture, text, texture and lighting and probably a few adjustment layers
keep working though, like titan said, check some psds/tuts out and youll be great in no time
