Art style of english illustrator Gary Chalk, mostly known for heroic fantasy art (Lonewolf, Hero Quest ...)
Trained with 47 HD artworks from Gary Chalk, his work is almost exclusively monochrome so don't expect color
Triggerword (if necessary) : garychalk style, you can use tokens like "monochrome", "greyscale", "ink drawing", "lot of details"
Don't use a photorealist checkpoint, "unstable ink dream" works pretty well.
