Nobody seemed to notice that there are two portraits here -- the primary one and the profile created by the shadow. This was very under-rated. I don't think many voters took the time to really look at it.
I like how you tried to do something different but in the end it just doesn't work for me. The biggest problem is the lighting, IMO. On the forehead you have this weird pointy pattern which doesn't look good. However, the lighting around the mouth down to the chin isn't bad and actually does provide some interest.
