I love the look of Mina and Momo but Bakugo looks like a psycho already.

Aside from the heavily weird fetish stuff that eventually plagues every franchise, I don't think there's any idea for a fanart that does not come out great with BNHA characters. They're just so diverse and each so likeable that you can apply anything and at least one character will be the perfect subject for it; if not several of them.
