Wonderful!
I'm pretty sure you're a beginner claymationist (I might have made that word up), so you shouldn't be judged on a similar scale as the Wallace and Grommit guys. That said, I would have liked to see a real story line, or at least the penguin doing something with the bottle.
Also, I don't much care for looped videos, so that's a downer for me. Personal issue, I didn't grade you on that.
