1 - dull from lack of sound
2 - too short
3 - badly animated
although dont worry, with a bit more experience, animating skill and of course sounds, youll make better movies, i can help you with the sound bit if you like, i got a microphone for recording sounds you need.
over time youll discover ways of animating better.
even watching a movie can help.
also check there arnt any screens where it flashes, like in the movie.
hope i also help!
