I like the color and composition, considering it looks like a top ref. The only thing I can't quite get is the lighting. From the shoulders, it looks like the light is coming from straight above. However, looking at the hair, it looks as though the light is coming from (my) left. And, though it may be because of the hair, on the neck it looks like the light might be coming from (my) right. Maybe I'm just tired and my mind is skewing things, but I just cannot tell where the light is coming from. Also, since there is no eye-shine, it looks like she's either dead/a zombie, or is under sort of spell or curse, like in those anime.
