The son of artists, Krull grew up surrounded by art.

His Danish father and Polish mother met at the Jan Matejko Academy of Fine Arts in Krakow, Poland. Following in their footsteps, Krull attended the Academy in the '90s for a Master's program.
"Most kids stop drawing at some point, maybe because they see that grownups generally don't really draw anymore," Krull said.
