v2 was an overfitted mess, so I'm not bothering to post it here. :)
This version produces more consistent, varied, higher quality output, and is a lot better at abstract ability icons. It also requires shorter prompts to produce good output. Click the 'i' icons on each image for prompt and settings.
I find that experimenting with different artist names doesn't replicate those artists' style, but it can add more detail.
For the next version of this, I may try finetuning Stable Diffusion 2.1 512x512 instead, to see if that helps it a bit with more complicated prompt comprehension.
