Old 2.0 Notes:
**READ FIRST**
ONLY use the prompt "flat color" if the model fails to apply its style to the resulting image. This newer model includes an alternative art style that can be triggered using the prompt "colored pencil (medium)". Use the prompt "sonic (series)" if you're wanting to do on-model Sonic characters.
