I couldn't say much about the flash, but it looked nice besides a bit of resizing on the guy on the right.
On the pivot, the reactions were nice, but you need to be less afraid of heavy spacing when things are moving through the air. A lot of it was too slow. I think a bit more accentuated easing on the bounces would be good too, meaning there wasn't enough difference between the small spacing and the big spacing.
Also, what did you set the options to when you saved it? The frame rate looked more like 12 than 16, which made it seem a bit choppier than perhaps it would have done otherwise.
Not bad really though.
Edit: actually it hadn't loaded yet. The frame rate is fine and the spacing isn't as small as I thought. The ball looked like it double framed on the floor before the bounce though, which needs looking at, and the guy at the start was under-eased and a bit shaky.
