This is my favorite kind of drawing style - where the ink bleeds into the paper and there are lots of little, intricate details. All training images were black ink on textured white paper, but Z-Image Turbo likes to add color to its generations. If you want to run with this, try adding something like "with subtle use of watercolor" to your prompts.
Settings I used for the gallery images:
Trigger: 1nk freehand ink drawing with subtle use of watercolor.
Steps: 9
CFG: 1
Sampler: Res_Multistep
Scheduler: Simple
As always, I'd love to see what you create with this. The best part of training these is seeing what the community makes!
