Does anyone know of good tutorials for Photoshop or Illustrator for designs like the ones on Threadless?

I would like to learn how to do designs like these:

http://www.threadless.com/product/1000/Runnin_Rhino





I'm a pretty good artist in the classical sense, and have a basic understanding of Photoshop and Illustrator (layers, bezier curves, blending modes, etc.) so I don't need those sorts of tutorials, just ones that show how to emulate those styles.
