Lensrental has some great advice
Quantity Based: One of the continual problems the AI art generation faces is in quantity, though it is continually improving. For instance, in the past, AI art would struggle with getting the correct number of fingers correct, or perhaps the correct placement of knuckles and joints in the fingers.
General Softness & Low Resolution: AI art takes immense computing power to generate, and it still hasn’t streamlined this problem. So often, AI art is limited in resolution and detail.
Repetition: To further expand on the tip above, AI art often uses repetition to help speed up the generation process. So you may see something copied several times over the same image.
Asymmetry: Asymmetry exists in all facets of life, [… if you] photograph the building so that it looks symmetrical across the plane. AI doesn’t understand these rules and often creates subtle symmetry shifts in its images.
