I like this style.
Judging from her eyes, I can assume she's either worried, troubled, or just been crying. Perhaps that's just me, but I think I'm right for once.
Never once have I seen any monochrome drawing looking so cool. It makes it hard to shade, but when it's monochrome, you don't really need to shade (correct me if I'm wrong here).
The background is black, and it really helps this picture. It's as if the shadows themselves are fusing into her...But that's obviously not your intention.
Am I the only one that sees the gray lightning bolt symbol, that is supposedly part of her hair? Yeah? Thought so.
For all of the aforementioned reasons (Except for when I was screwing around and adding my thoughts), this picture earns a 10/10. 10/10 doesn't need rounding, so you also get a 5/... Oh, wait, you're not scouted yet. D:
