This looks more like a snapshot. I think you should have gotten all of him in the shot, with less wall to the right. Maybe also a different angle. Also, try to make the largest side 640.
The shot is rather blurry, so I had to take off points there. It's also quite small. I do like the concept being worked on though. Are you sure it's napping though? It looks very posed. Plus the part of the head is chopped off! Maybe cropping out the ladies at the corner might work a bit more and giving the guy his head back. For this shot, I gave a 4.
