Akira Toriyama
He does the art of the Dragon ball series and is the reason why I started drawing in the first place. I didn't draw because of the art style but because of the action scenes that Dragon ball had.
Jamie Hewlett
He is notable for his works in Tank Girl and Gorillaz. There have been times when I draw in a comic art style and so I've used Jamie's art for references because of his mature/punk art style.
Sui Ishida
He is known for dark fiction series Tokyo Ghoul. His genre is about tragedies and so his artwork is dark. I like the feel of dark/punk art styles because of how out of the ordinary it is from other artists that make happy/clean looking art.
