Most of it is very well done, but the neck is much too far back. If her head and neck were moved (or just cover her neck with her hair) this would be nearly perfect. The shattering mirror background is a nice touch, though your signature gets in the way a bit. Move it more towards the top left corner. The eye we can see seems too purple in contrast with her hair, make it more of a light pink. Her belt seems to be floating around her waist, and the parasol could use more detail, but all in all the neck is the only major issue here. Everything else is done well, and I hope to see more from you.
