I found a way to run Stable Diffusion on my own PC rather than using the various web hosting services. My first prompt was "A grapefruit contemplates the meaning of life, oil painting in the style of Michaelangelo and DaVinci." I wasn't pleased with the first result. Not only does it look as if the AI merely cropped out a slice of existing, human-painted work, it doesn't capture my intent.
So I rendered the same prompt again, and Stable Diffusion came up with this much more pleasing (?) result.
