Execution
That's what you need to work on.
However, overall this was certainly a good flash. Your music selection was fitting, although I believe you could have used some additional sound effects. The graphics were quite good, especially the rainforest scenery. Great job on those landscapes, as well as the panda. The animation was a bit choppy at times, and I thought the frame rate seemed a little sluggish (I suggest 24 fps, if you're not already using it). Generally speaking though, the animation was acceptable, with a couple great instances (such as the panda's walking animation).
About the execution: this flash revolves around an "escape." Therefore, you should focus on animation techniques that give the audience the illusion of speed. Imperatively, you need that higher FPS I was talking about. This will smooth out
your tweens, and will allow you to create more chaotic scenes.
Regardless, this was a near-excellent flash with an ace storyline. Your head's in the right place, man. Keep at it.
