I'm almost done my first scene, but already moving onto my second; a dog walk to run to jump. Taking the Jason Ryan approach, I've drawn thumbnails in Flipbook first. If you're a 2D animator wanting to branch off into CG, this method is very logical.
Anyway, I'll post both of the rendered scenes when they're ready to be seen. For now, chicken scratched keys...
