Flux is so frustrating to me. Really good prompt adherence, strong ability to keep track of multiple parts of a scene, it's technically very impressive. However it seems to have had no training on art-art. I can't get it to generate even something that looks like Degas, for instance. And, I can't even fine tune a painterly art style of any sort into Flux dev. I get that there was working, living artist backlash at SD…
Diversity is a double-edged sword. It's a desirable feature where you want it, and an undesirable feature everywhere else. If you want an impressionist painting, then it's good to have Monet and Degas in the training corpus. On the other hand, if you want a photograph of water lilies, then it's good to keep Monet out of the training data.
