Hmm...
'Twas quite nice, actually. A few improvements here and there, and things will be fine. I think you could make a serie of this.
Artwork: Not the best, but will do. Try adding a bit more detail here and there.
Animation: Not that good, try getting it a little bit smoother.
Music: Voices were good, but maybe a better microphone will improve it.
Story: Overused joke, but it was fun to watch.
4/5 7/10 for you. Nice job.
