Start your prompt with 'Charcoal Drawing'
The versions came in quickly, but this 1.1 might already be my end point - it's pretty much exactly what I was envisioning for this model. More realist and detailed, more flexible, yet still visibly charcoal rendering. With a big caveat:
The appearance of charcoal diminishes dramatically with a lot of checkpoints other than the base SDXL.
You can still get some cool imagery, but it's going to lean toward black-and-white photography or grayscale paintings. If you really love that charcoal look, stick with the base model.
