As i had understood the setting is modern, sci-fi but with some anachronism and fantasy elements, kinda what FF games do. With tech powered by magic energy and stuff like that. Ancient cultures jumping to futuristic setting.
Is with that idea in mind that i´m sketching also, i think that elements are going to clash if the characters look too traditional fantasy-like.
I at least will try to do an enviro, because i so never do them
