Looks amazing!!!! It looks really well constructed, and you could really keep it like that if you wanted to.
Possible improvement suggestions:
-Straighten the wig a little so it lies a little straighter or trim long bangs into it (I'm unsure of which version you're going for, anime or books)
-Add more detail to the bottom of the underskirt
Your metal pieces look beautiful and you also chose your fabrics very well.
