Over all, not bad. You're telling a good story with a reasonable visual technique... It's admittedly a little primitive, but that's as much a style question as a quality one.
There are a few typo's so some proofreading effort wouldn't hurt. And you have progress to make in visual effects, but these are small steps and both come with experience. They are worth mention of course...
You seem to have the audio sync'ed up well for the purposes, and your animation is fluid. I also like the control button that lets me read the whole line before letting the next step in action. I think there's more that can be done this way, and I'd like to see what you come up with as you explore it.
Don't forget to breathe, relax, and keep on keeping on... Animators animate... :o)
