Two things are working against you here. A cluttered background with dark regions obscures your subject and competes for the viewers eye. Also, the pose of your model hides the stronger outlines of her face, making for a less distinct shape and much less impact as an image.
Little grainy, and the background would be better if it didn't have the distractions in it... maybe an over-exposed background and just a silhouette of the singer
This photo suffers from being "flat".
It needs more tonal range and composition which excludes pot lids in the distance. Hint hint.
Oh, and that song sucked!

Oooops.
Did I just say all that out loud?
