Okay, firstly, before I go off and crush all of your dreams, I just want to say that I liked the film, and thought it was a nice little animation. I would certainly watch it again.
Mistakes: The requirements of a Dictionary series films is that it must be absolutely silent, lest some sound effects that help contribute to the definition of the word. So no music, and no "wasteland" sound effects. It doesn't contribute.
As for the animation, the minifig seemed to move back and forth on the white expanse too much, especially when he was picking his nose. I couldn't tell if they were camera bumps, or if they were minifig bumps, so I can't really say. The switch between the two minifigs was kinda too fast. You ought to make it last some more frames, like 10 or 15.
That's all for now. I hope you improve your animation skills.
