good focus. a bit overexposed as the white of the shirt is a bit too hot and pulls the eye away from his face. perhaps another angle could have avoided the wall molding that cuts through the center?
The top of the shirt is overexposed which is a bit of a distraction I think. I also find the angle of the background cutting right through the mouthpiece a bit distracting too.
sorry, but this comes across to me as a nice snapshot with a good camera. get some books on composition and i'm sure you'll be able to come up with some much more dynamic images.
