The right knee and upper leg are really flat, and it doesn't seem you put much focus. The hair bugs me a lot, it doesn't really look like two different hair colours, but more like she stuck her head in a slushy machine. Another thing you should focus on is folds, folds aren't just random and all over the place and don't distort the shape of clothing, especially like you did at the right shoulder. And her eyes don't match up, the left is slightly higher than the other.
