Need Point.
I think this rule:
"Your movie must not be a pointless "demo" or "preview" without any redeeming qualities."
applies well here. A guy pulls up in a car and walks off. Sure the drawings were "ok-ish", but the animation was just a bunch of tweens. The way the guy gets onto the side walk was just awful to watch by the way. I'd like to see 3-d looking turns onto the side walk, yes that means you'll have to go frame by frame, but it'll look awesome compared to some guy just "floating" onto the sidewalk.
I also suggest you make a full length movie to submit because a "plotless" trailer won't go anywhere. I've seen it happen a thousand times someone says they're gonna make something awesome, but instead they end up making a trailer and abandoning the project.
