Not too bad for a first timer. Though, I will give some critique to this film.
The animation was pretty good, but I think the framing was a little off. Instead of converting it from 15FPS to 20, keep it at one consistent frame rate. There were also some set bumps and light flicker, these things are simple to fix though. Just tape down your set, and set the self-timer to 2 on your camera (If you have a camera that uses manual shutter). And keep ALL the settings on your camera
MANUAL
This is very important to stopping light flicker, as well as changing the white balance to whatever type of lamp(s) you're using for animating. The effects weren't that good, but they definitely were not the worst effects I've seen (I being one of those crappy-effects contributors). Now, for my un-official ratings (which I have not done in quite a while...):
Overall: 3
Story: 2
Animation: 4
Cinematography: 4
Effects: 1
Sound: 4
