Wow, that's actually pretty good for your first. You need to work on alot of things though. Nice work.

And those things would be:

Wobblyness
A plot
Particles
Easing
Anticipation
Force
Physics
General movements.

Get workin..

Way to be subtle krome, if you need clarification on anything
krome said you should work on just ask.
Otherwise he basicly got it all...

You know, general movements and physics aren't that different from each other :S

Yes they are.
General movements are...well moving running, jumping, punching, etc.
But physics are how his arm will fall after a punch, or how high he will jump.
=D

I say it is great for the starting relm, i'm defenitley putting this in my novelty collection with all the other animators and thier famous work.personaly i don't exactly bieleve sweeptl knows of we are saying. check prospects thread it is some were way back it will teach basic physics i geuss. i'd also recommend To study up on frozen pheonix he has alot of good flash animations, get some insparation you know

For your first it was excellent,
but it was way choppy, and it lacked easing. Physics were off, as well.
(And everything the others said.)

Ah, and weird storyline.
