This nasty fellow pilots The Worm - the boss you're likely to encounter and the end of the third chapter of the game. Though I'm yet to write any of his dialogue, he's clearly extremely battle-worn and quite possibly a little bit nuts. :)
This was hand drawn on paper in about five minutes, then quickly photographed and digitally painted in about an hour and a half.
Finally, I sped up the footage so you get the complete process in about ten minutes. Enjoy.
