great posing and photo. whatever that is on the floor is very distrating, maybe a different angle to avoid that? also bouncing the flash a little higher up (if it's not an on-board) would have helped as well.
The tones on the mans face seem odd, a bit on the pink side. His office isn't very appealing, rather boring actually, so I don't think it is the best choice for a background, or maybe just from this angle. With the title, I think having him sitting down, maybe taking a phone call, would add more substance to this image. Also, the metal on the floor is very distracting. You could either try putting something over it or clone it out after the challenge...4
