Overall, I liked it.
I enjoyed the unique animation scheme. The colors are very visually pleasing, without sacrificing visibility.
On the downside, the audio, while good, is extremely hard to hear. I had to turn my speakers almost all the way to hear, particularly when the little girl was talking. Then when he fell and started screaming the sound got really loud and I had to turn it down real quick. I realize this was probably for dramatic effect, but you should work on that a little. Make it louder in the beginning so the viewer doesn't get that big boom of noise all at once after they've turned their speakers up.
My only other suggestion is that it be made a little longer with a little more story actually in the animation and not so much explained in the author comments section.
Other than that, great flash. Keep up the good work! :-D
