The detail on the eye is wonderful, but I think that black something is a bit distracting especially considering that there is more picture under it. Maybe if the picture just ended with black on the bottom without more light?
Lovely detail in the pupil - your use of sepia really brings that out. What is the bar across the photo though? The frame of a pair of glasses? I really like how you lit the face, making the area around the eye a bit blown out - it really seperates the darker part of the eye and draws the viewers attention to it.
