Check out the Prompt Guide:.
For years I've hosted websites where people can go and find a suitable avatar/portrait for their roleplaying character, rather that be for Dungeons & Dragons, Ars Magica, Vampire the Masquerade, etc. In the past I've compiled other peoples art and converted them to tokens. With Stable Diffusion this allows me to create portraits and character art with the click of a few buttons. Experimenting with the prompting to see what I can get. I've created a few checkpoints for usage with the Automatic1111 GUI Stable Diffusion build, or any other GUI that allows custom checkpoints. I'll be adding more as I create them.
