I've never known how to shade, so the horns were really where I tried to practice, it took a good 45 minutes to do both, plus learning how to shade them. I've been drawing anime for years, starting with My Hero Academia, branching to Dragon Ball, and random One Piece and Fairy Tale ones, so here's my Genshin contribution. I might color it, but honestly, it looks kinda good, and my past experience is that when I color them, they don't look as good. I've also never done digital art before, I've always just done little sketchbook drawings and ones on binder paper, so this was a workout.
Anyway, if you guys have a character I should try to do, I can do requests...maybe.
