My thought was the same as gome - fantastic lighting. For me the light in 1 and 3 are the best. I don't like it quite as much in 2 and 4 - it's not bad, just not as good. Nice job on the mirror effect on 5 - took me a little big to figure it out, although I think I can see it a bit in his foot on the ground - almost looks like he's sinking into the cement.
For suggestions, while the light in 1 and 3 is my favorite. I appears as though he was trying to give the kinda cool, tough look. But he just looks plain ol' angry. #4, I'd like just a little more room around him. The phone pose is 2 is kinda goofy and lastly the way both his shirt and jacket splay out in layers below the buttons looks kinda weird - like bird feathers or something.
Anyway, those are my thoughts. But all in all, I think you did a really nice job and I kinda nit picked these to death ;-)
