Wuh? A bit wierd.
Why would Kaneda ask for help with hitting a clown?
Suggestions:
Draw a bit more detailed. Loop the sound. The clown should be drawn in the same detail as the motorcyclist if you can. I'm not sure it would help the rating of the flash, because this piece really need more story :) (maybe akira fans will appreciate it more??)
Don't take it too hard though :) and keep making flashanimations!
