Good artwork but animation needs work.
The art was great. Mainly due to the shading. Try adding some more lighting effects. Just a simple low set yellow to white gradiat works great. Color bleeding is good effect too. Figure out the most common color of the scene/shot then cover the entire stage with it and set the alpha really low. (Like.. 7-15ish) Adds a great effect as it's easier on the eyes for viewers.
Your lip sync needs a lil' work. The size of the mouths aren't a problem at all. I could tell the audio was off a bit at times. Just try setting the audio to stream or changing the flash publish settings audio bit rate down to about 46-56 and quality to medium. It's rarely noticiable and works great. Add a few more mouths. All I saw was the standard opened, closed, and teeth mouth. No "O" mouth.
Eye movements and body movements durring lines are good too. The one characters eyes and brows didn't move at all. Which gave a stale effect.
Also: For your shots. You instantly had a close up. If you don't have a Vcam I highly reccomend it. If you do but are simply just cutting to a close up don't. Zoom in even if it's a 2 second zoom. It's easy on the guys and holds the same effect.
And finally... Rudy you dog. You say you hate mullet but both those dude had mini-mullets goin' on. :3
Keep up the good work man. Your lucky to be young. Ya got more time to practice. :P
