You don't need to be totally "on-model" to storyboard my cartoons, but you need to capture the essence of the characters. The basic proportions and the attitudes. You can leave out details, as long as you have clear posing and acting and continuity. See how clear the silhouettes are too.
These links may help you if you are a storyboard artist and are interested in working on the show.
