Those shoes don't work, maybe try something like Raisin Ribbon Candy and layer under some black tights. Wisteria Sea could work too, and it's go with the whole witchy thing.
The arms blend into the hair too much, and don't fit the expression, use black arms instead. Libelly Chauntelle would go with the facial expression. You could also change the eyes to something open and just use a recolor of the arms you have now, or something. I also really don't get why the big black wing's there, and the white wings+tail out the back don't fit with anything.
6/10. It's got a decent base.
