I dig the style. I only have a few things to recommend.
1. The arrow would look better foreshortened IMO. Even if it's just very slightly. It theoretically could have flown in at that angle, but it just looks strange being so perfectly on an axis parallel to the viewing plane.
2. A bit of blood splatter around the wounded eye would go a long way. Just a couple of tiny marks outside of the blackness, even.
3. I keep going back and forth on this, but I kind of feel like the shape for her right shoulder (our left) could be extended out a little bit. It looks like her center of gravity is a little off, and almost like she's straining to stick her head forward. That actually adds to the strangeness and odd appeal though, so I don't know if it's even a problem. Hah!
Anyway, nice piece. *follows*
