The only thing that really strikes me as off is that the head is cocked oddly back on the neck. It's not so bad that I couldn't be convinced that's what you were going for, but it still looks off. I might push her face forward just a smidgen, and possibly lop off a bit of the volume in the back of her head, and round the head out a little. It just looks awkward, having all that hair extend so far out from the body, especially when it's so square on top.
