Ooh that is a nice one. And off to my Fan Art Folder it goes. ^^
I would go for a more genderless look normally, but this is Fan Art, so why not slightly more feminine features. ^^
You did get the Hair shape really well, though I would tie the Fox Tail in a way that points more down so that it isn’t looking like a top knot. It is more inspired by the white wigs people wore two or three centuries ago, with a bit of Anime mixed in ofcourse. 
Always great to see different interpretations of what I imagined.
