Nice First Effort
The humor content was pretty good for the first time around. I especially liked the "flast card" element. That was the highlight of the piece. I got a few chuckles out of it, which is good. That shows the ability to tell a story and carry a joke.
Of course, I gave this a 5 for a reason. And here goes:
Visuals - the mix of sprites, shapes, and clipart looked disjointed and a bit sloppy. You should make sure your different visual elements blend together. This could be a problem when you start doing animations with motion.
Voice Acting - pretty good for a first timer, but it sounded like you were too close to the mike or using a cheap mike.
In summary, it looked pretty bad; it only sounded OK, and the humor was pretty good. Work on the visuals especially and you too can soon be turning out really good flash animation.
