Looks good.
One thing to try, to see if you like it, would be to use that same lighting scheme, the two side/kicker lights, but let the shadows get darker for a deeper ratio. That would mean that the front of his face could get pretty dark, but if you position the side lights just right, you can get away with it, and it looks pretty 'bad ass'.
Then, to step it up another notch, get him wet so it looks like he's sweaty. Have him rub on a bit a baby oil (or similar) then spray some water and it should bead up. I guess you could mix in some dirt on the face and jersey to really take it to the limit.
