Yo! You need easing, also your stick figure doesn't seem painted right.

Easing is right.
Animation without easing is lifeless and robotic.
Definitely good for a first in flash.

What the others said about easing,
and also he looks very stiff, you used free transform a lot
and he hides behind the canvas at the end so it's difficult to understand what he's doing.
The jump seemed to go too high with the kick in comparison to the launch

what do you guys mean by easing??!

It's the gradual increase or decrease in spacing between frames.
It gives animation life. Feel free to look in the tutorial section for easing.
