Submitters should study this one.
Well done animation, well drawn charcters, scored so that the music builds the mood. Interesting premise and the guy is willing to spend some time developing characters as he sets up the story.
I've seen worse on Cartoon network. This is how it's done. And, while it took a while to draw those characters intially, he can use the same panels over and over again as the story progresses, merely changing background and detail to make them seem new. That's how Tex Avery and Walter Lantz did it, except, they didn't have Flash to work with.
Compared to 99.9% of submisions. this is Citizen Kane.
