From Laurent Linn: "I’d say they should be sure to include illustration samples that show narrative storytelling for sure. Portraits, still life, landscapes, etc., are interesting but won’t show how an artist will interpret a story and bring characters and a world to life. At the same time, sometimes different kinds of art will spark interesting conversations, so I don’t want to limit them too much. They should just include their best work!"
