Here's my cartoon dog. Could use some tweaking here and there. Really enjoyed the tutorial, never worked with NURBS before.

Big thanks to Kurt for the tutorial, good work! (You could increase the mic volume or talk louder though

One problem: when I render with Mental Ray the Sub-D model won't render, and I get a error message:

Error: (Mayatomr.Geometry) : polyToSubdShape1, non-quadrilateral face in subdivision surface base mesh not supported, ignored

How do you fix that?
