Here are a couple costume edits I just finished.
Rewrich Wallach - Dark Zero Edit:

I didn't put a lot of time into this one.
Original:

Shurelia - Judith Volltone Costume:
To be honest, and don't get me wrong, because Lita is one of my favorite Atelier series characters, I've always felt that it would have been better if Shurelia had a Judie costume instead, or at the very least along with the Lita costume.
Since Aurica had a Marlone costume and Misha had a Elfir costume, I think it would have worked better to continue with the older games theme, and plus, Judie had silver hair, Lita didn't.
Anyway, enough with my opinion and on to what I've been rambling about.

I only put a couple hours into it, so I hope it looks good.
