I like this a lot, there is something throwing me off a bit though. The bottom of her hair. It took me a sec to realize it was her hair, not cloth. It wouldn't all sweep to the same place over to the right like that, unless it had been cut on an angle. the bottom part of the hair should end sooner than the top part of it. Maybe try shortening it and chunking/whisping it up a bit? Hair doesn't usually stay as thick at the bottom as it is at the top. I hope this makes sense! lol.
I love the detail on the 'skirt'!
This is a super crappy sketch, but maybe it'll explain what I mean better:
