One of the most awesome storyboard artists I've ever come across is Toby Shelton.
He's got such beautiful lively drawings that are so communicative and expressive that after looking at his storyboards you don't feel like drweamworks NEEDS to make a movie out of it. They're so self-explainatory. His lines just flow into one another, creating strong forms and expressions that one can immediately and strongly relate to.
Here's his blog - http://tobyshelton.blogspot.com
Check out some of his work for all inspiration.
