I like the subject's eyes. His expression and his hands tell the story.
I think cropping tighter will help make those elements even stronger. Lose the drink machine on the right and some of the space on the left. Crop tight at the top (even losing the very top of his hair). Crop the bottom, but leave some breathing room under his hands.
The slight lean in the door frame on the right of his head is mildly disturbing -- you might want to straighten it, or not (I just nitpicking )
