If you like art with a decidely cartoonish style and ubergeeky subject material, you'll love the work of Spencer Brinkerhoff II. While the artist hasn't updated his site since the 2012 San Diego Comic Con, he still has plenty of great pieces up there to entertain.
While Spencer is best known for his work on the Star Wars Celebrations, I'm a particularly big fan of his takes on classic cartoons, which really work with his animated, cutesy style. Maybe if we give him enough love we'll get him to head back to his site and update it with some more recent work.
