Interesting story and the backing track is good but your animation is too shaky. You should try building your props out of something sturdier then clay so they don't move so much. For example, the table you used could easily be replaced by a small wooden structure that you glue to your base. This would prevent it moving around and also your fingerprints on it. Also, turn the frame rate up. It looks like you shot it on 3's maybe? Stop motion looks particularly poor if shot on anything less then 1's. Still nice to see someone rocking clay though! Keep going!
