( Not my Model )

This is a watercolor style that features loose and sketchy ink lines and messy watercolor edges. Subjects tend to have a cartoony look. It's good with slightly top down views, but isn't limited to them.

You only need to add "n0vuschr0ma style" to your prompt to trigger it. If you'd like to emphasize the sketchy look, try adding "watercolor sketch" or "watercolor and ink sketch".
