I dunno what this is but it looks amazing!!
I haven't quite got to grips with this website yet so I'm not exactly sure if you are talking about the costume as a whole or a particular image :P
But the costume is a custom character I designed based on the work of Junko Mizuno a graphic artist.
Glad you like it though :) xx
I've gotta ask, are any of those photos the reference photo or...? If they are, then I can't tell the difference between you and the real deal, which is fantastic!
