If you're planning on animating, you're gonna have to ease up on the shading, at least at first =P
I mean, it looks really wonderful [especially in your painted work], but it'd be a huge pain to do it over and over again for each frame of a flash... Using simple shading would let you focus more on the actual animation =]
Anyways, this was really good for your first try... Definitely not as bad as you say it is in the description.
Good luck :D
