There are some things that Stable Diffusion does surprisingly well. One thing it is really bad at, though, is counting. It, and other art-generating AIs (like DALL·E and Midjourney), are notorious for adding extra fingers, extra limbs, extra abs, extra petals, etc. Another thing AI art generators are bad at is patterns. They can usually identify parts of the pattern, but they rarely reproduce the pattern in its entirety. I present an example below. Stable Diffusion was able to draw a variety of sports balls. It generally got the shape and color right. But the patterns of the seams were always distorted to some degree.
Just for fun, I threw in some explosions and lightning.
