Does Joy look like someone you know? She doesn't. She's a creation of Stable Diffusion and is here for your use in your prompts.

Important thing: Joy has a tendency to skip race to being white in a lot of popular models. She appears exactly as intended if you add words like "black" to the prompt.

I recommend you use ADetailer to show her at her best.

Instead of my faceapp method, Joy was trained using the generating from prompts methods described here, but with my own approach to tagging and training.
