Phew! Stunning render! Love their new wings. Hope you don't ,imd me saying that I still prefer the younger looking Remilia. Don't get me wrong your more adult/mature Remilia is fantastic, it's just a personal preference!
Look forward to more. Incidentally are you planning an adult/mature Flandre?
I wouldn't mind seeing a mature Flandre. Not one bit. I'd actually like it, but that's depending on whether I like the picture or not. Which I usually do when it comes to your art style. It really is very good.
