Would you mind posting up the BEFORE pic? We have no idea what you started with...don't get me wrong, the pic looks creepy as ever, but it would be cool to see exactly what it is that you did.
Wow, looks pretty sweet. There isn't anything that I see wrong with it. Like my friend, Martoch, I am no PS expert. To me, it looks technically sound and the only things that could be changed would be based on what you are trying to accomplish with the image (what you have in mind). Looks great!

It would be nice if you made it a touch less dark. Enough so that at first glance people will know its a face. I had to look at it a couple times before i knew exactly what it was. Really nice job on the manipulation. Its a SWEET job you did!!!
