Well worth the 11Mb!
Good thing you got the upload size increased, well worth it. This is hopefully a groundbreaker for NG, though I dont expect any of this calibur to be making an appearance anytime soon.
Animation is slightly different, everything is smooth other then Green's walking animation, which involved about three frames. Whether you cut down on them or had to converve filesize I'm not sure, but a smoother Green animation would have made it a touch better.
Pausing inbetween scenes is essential for the making of it, so I wont even bother bringing that up - only that it could be a little less, but as if I'm gonna penalise you for that, I'm not that cruel.
Original script, original idea, original characters (Though that human in there looked like he was stolen from another flash animation, am I wrong? hehe...), all put to good use in a groundbreaking style of flash submission.
Awesome work, heres looking at many future submissions by you, and others out there willing to make a decent effort at this sort of thing.
Voted 5.
Btw: Nice job with the credits, I managed to read them all the way through ;)
