Trigger word: "sketch". No negatives needed, no long prompts needed. it just works.

Optional Negative (changes the style in a minor way):

Deformed, unrealistic, bad quality, grainy, noisy, plastic, hazy, low contrast, cropped, close up

While it can do ?????? to some extent, keep in mind it's still sketch style.
