Nice!
Nice job, It's interesting to see animation like this, as opposed to the redundant flash animations (don't get me wrong, I love flash animations, but it's nice to see something different like this once in a while).
Oh and what the person wrote before me about getting a new microphone, I believe what he was thinking of is a pop filter. You can usually get em for around $20 - $30 at music stores. Those are what recording studios use to get rid of hard P's, S's, etc. The microphone is fine quality for the application.
Your voice was great too, by the way. Perfect for this kind of thing. Great job! Keep it up :)
