Very nicely done...I would agree about the right side of the hair. It could have some darker areas in it. There is only one area that bothers me of this piece, it's a compositional critique, nothing really big though. The top of the hair either should have had a space between the top in order for better flow or should have went off the page more to separate the two halves of the page. The space between the top of the hair and paper would probably been better but if matted and framed right it will work out just wonderfully.
