I think it would help the image if the background was less distracting. I like the pose and what you were going for though.+1
+1 as well! I dig the creative direction.
What I would try: have him put his hands on his hips in an aggressive position. I'd try to draw less attention to his chest. (No offense meant. Just trying to be constructive.) Also, lower the chin a bit so he's looking up slightly.
I think the lights on either side of his head distract because they're actually not strong enough! Maybe try ramping those up just a bit...just to see what happens.
As for processing: I like the edgy look in sports portraits. Try a slight desaturation, then run a high pass on a layer merge and set it to "soft light" blending mode. (This is a slick way to sharpen an image.)
Hope this helps!
