I think I'm learning more from correcting these than from the actual drawing. In the corrections I see how the perspective works and how the initial action line and placement of structural elements help build the final form. In the animation stage I'll be using the skeletal puppet to get the movement right first, and then going back at a later stage and adding the body details. The first pencil tests should be just animated puppet-like stick figures.
I hope to have a syndicated cartoon to post here later today. Stay tooned!
