Well Done!
What most ppl don't realize is that Claymation/Stop-Go-Animation, is very hard and time consuming. Just 30 seconds of animation can take several days. I personaly think that you did an outstanding job for an amature! Well done, and keep it up. Though, in the future, you may want to work on creating more complicated/detailed figures/characters, and perhaps investing in a higher grade camera and better lighting. If you do this, and keep working at it, you may even have a chance at doing this at a career.
