My fourth mentor is Mike Walling. Here’s a photo as well as his brief bio:

Mike Walling
Mike got his first taste of animation at PDI where he worked as a production assistant on Antz and then as a render wrangler on Shrek. Using the rigs and software at PDI, Mike was able to put together an animation reel which landed him his first gig as an animator at DNA productions in Dallas Texas, animating on the Jimmy Neutron movie. Three years later he was off to Blue Sky Studios to work on the feature Robots. He is now a senior animator at Sony Imageworks.

He’s been great so far, and if you want to see some of his work, head over to his site:
