Not bad at all.
This is pretty decent. The graphics were cool, the concept was pretty original. I would suggest using some minor actionscripting though to prevent from having to redo the entire area any time you revisit.
Essentially, you could just nest a movie clip in the main timeline that you could resort back to, so any changes made to the movie clip remain.
Just a brief tip man, it'll make these cartoons a lot more playable.
Good shit.
