I like your c4d use as well as lighting effects, they're very natural and while chaotic, it's an organized chaos. I do however think that your focal is losing it's attention to that one blank area above her which is detracting from her purpose. You also put a gradient map on top of the whole sig that made any form of depth on your focal and effects drop in effectiveness by a good amount. I suggest either lowering it's opacity, or throwing some sharpen/ blurring layers atop this one to really bring out the folds of her hair, the lines below her disappearing into the background, and a few other places too.

I'll be around if you need anymore help.
