Very nicely done! Her sword and clothing remiends me of "The Bride" from 'Kill Bill' (an awesome movie, by the way). Though, I would highly suggest changing that symbol on her fore-head. Not only could you think of something that looks cooler, but it also sort of looks like a Satanic symbol with the way it is now. I actually think the character would look better without any sybol(s) on her fore-head, but that's just my opinion.
