After looking at your image for a few minutes now, I sometimes feel like I am looking at two separate images (even though I know I'm not). I think it's the light of the face "fighting" with the darkness of the hair. not sure if that makes sense to you, but that's how I view your photo.
I have to be brutally honest here. This looks like a shot you'd get back on a roll of film from a camera that was passed around at a frat party after all the girls had left and the beer was gone and there wasn't anything else to do. The lighting is harsh, the composition just does not work, and the focus seems off.
