I'm guessing you used just the one light? It's created some quite strong shadows, which a second fill flash or reflector would have helped to reduce (or maybe this was the look you wanted, if so ignore the comment).
As for the crop, you could lose some of the right hand side and bring it to a standard 6x4 crop IMO.
It's a nice shot, though he's squinting a bit and it's like you've caught the start or end of a smile.
