I dabble in drawing and I find LLM images (and maybe some non LLM one) abhorrent. As for why, the reason I can think of are: no consistency (perspective, small details, and color theory) and too much details making it a visual noise. In most painting, the artist will have a subject that is most detailed (to draw the eyes) and from there, the lost of details will follow some kind of logic. This is how you pinpoint what the artist is most interested in. LLM looks like a filter applied to a montage of pictures.
