Man, we need a good lighting tutorial. Everytime I try to use the dodge/burn tools, it always ends up greying it out. Excellent work there. It's make a good desktop if it were bigger.
Very nice image, but I'm going by what you said in the first post and trying to point out the stuff that could be improved upon, hope you don't mind. Its a nice image, good lighting but the character still seems very 'blocky' try rounding off his shoulders a bit next time. Also the perspective on the character lying down is a bit off as well. The hair could use a bit of work, other than that great!
