Hey, that's looking pretty good. :)

If you're going to be doing more animation, then you should seriously consider this book: http://www.amazon.co.uk/Animators-Survival-Kit-Principles-Stop-motion/dp/0571202284/ref=sr_1_1?ie=UTF8&s=books&qid=1212705216&sr=8-1

Even if you don't actually do any animation it's a facinating book, and really easy to get through.
