What better to practice drawing than with turning your poor defenseless friend into a cartoon character? I think this was from 07/08 when I was trying to bulk up the portfolio a little (the "Huuuh!" is an inside joke, that, no, I don't understand either).
The cartoon on the t-shirt isn't random, it's a doodle by Nara, also on the Fantomas Suspended Animation album.
As well as interesting commissions, I hope to someday visit the planet Mike Patton came from.
