I quite like the first one - it sets the tone with the football motif very nicely. The only small nit I have is that his right eye are a little dead. Other than that - a well executed shot.
#4 is a very strong portrait - great pose and good control of the ligting
Really liking #1, but one thing nags me about it. If you could have flagged the lower end of the light, you would not see the light stands and power cord. Aside from that, great shots.
