Good

Needs polish. Looping is a bad idea. Voice is good. Animation is great for stick-figures. Add some color, some background, make the bunneh look way crazy bad (since the comparison is a stick-reality), and maybe a song at the end with some credits or other nonsense. I gave you a 5. I think you have potential. Save this flash!

Not bad

The voice acting was pretty good. The audio quality could have been better, which you can do in flash by going file > publish settings > flash > then up the audio kbps.
The animation was alright, but the dropping in at the start was kind of *too* unrealistic. You could have made gravity present by using a tween with -100 easing, or have him walk in.
As a whole, it seemed a bit lacking. Things like a background, full characters and colour. It was also a little short and could do with more of a punchline.
But you did a reasonably good job for your first flash, so keep at it and strive to improve.
