OK so my overall feelings on AI art: it absolutely steals original work to frankenstein an art piece. I don't think it's a GOOD thing and I think AI art does more harm to artists than good IMO.

The only usability I've seen AI generated images has been making assets 2D for horror games that were SUPER hard to make out/abstracted from the original source.

TLDR: I think you'd be better off making a reference/insp board and trying to visualize something that way, it feels a lot more organic vs. using stolen artwork (ex. anime characters generated from fanartists.) I am far more concerned about the ethics of AI art and how it affects artists.
