That's a great shot. Simple, strong, effective. Excellent model.
I'd prefer some separation from his head from the background. Unflattering reflection on his forehead too. Why not shoot at a lower ISO and pull the lights back instead? Was a lot of sharpening done?
unfortunately it was shot using the modeling lights, which aren't strong enough to allow me to reduce the ISO. In fact, the shot is quite out of focus, so yes, alot of sharpening was done.
