That video looks like designing a video game asset to me, or putting together a map for W40k match. Part of that might be some personal bias because I don’t really have an appreciation for depictional fantasy art.

One thing I’ve noticed with AI art which I think is holding the genre back as a whole is a focus on realism, especially photorealism, or at least staying vary far away from abstraction. Other styles are largely stolen - like, I’m sure it’ll be happy to make a Basquiat of Ashoka Tano or a Klimt “The Kiss” of Anakin and Padme. But that’s the options as far as moving away from photorealism - the style of artists that already have their stuff in museums.

This also seems to tie into the “AI helps people who don’t have the time/ability to develop drawing skills” argument - that the only way many folks can even conceive of making “good art” is getting really good at drawing photorealistic faces.
