This is Jason Seiler. He is a fantastic illustrator and character designer. I've been a fan of his work for years. I've liked caricature all my life, but this guy's work is very inspiring. I've done stylized portraits of most of my favorite artists. I don't know why it took me so long to do one of him. You can find his work at jasonseilerillustration.blogspot.com Hope you like it.
