The same concepts that also overlap with designing ai genres art. which is my pointW
Framing is set manually, different generation zones and is quite literally composition.
Adding skeletons with control net to fix a pose, again composition.
Choosing one of 100 different generated sky backgrounds is easier if you know color theory and recognize realism or lack therefor.
Pretty much all mediums of art have these indeed. So does comfyui. Ergo creatively designing ai generated images is art.
