Too long
With a little experience, your animation and art will get better-
One thing I think you should work on is the length. There were a lot of unneccesary scenes, and the voice actors talked way to slow. Add in some subtitles and speak faster. Jokes can come out faster, too. Quicker jokes keep the audience laughing. It was a pretty good script overall, though, just try not to make it so long that we lose interest.
