Drawing, Hair

I've been working on the hair today. I'm a little worried about how it's looking. Usually taking a photo helps me put it in perspective. It's a way or separating myself from the drawing and getting a new view. I'm feeling a bit better about the hair now, though I still think it needs some more work. Also now looking at this photo I think that I might want to just leave the background blank. The white background doesn't look to bad, though I'm not sure still.
