This is an improvement from the original.
I never really expected you to elaborate on your concept, but you did it quite well. However, it's just a trailer and not a proper pilot.
Animation: Interesting mix between 2d, 3d, and photograph backgrounds; it looks like something that Ralph Bakshi did back in the '70s, but in a good way. Your animation has improved considerably since you made the original five years ago, along with a clever usage of Flash gradients. However, your colors could have used some improvement.
Audio: The music that you chose was excellent and fit the situation quite well; but I think you could expand your music roster by checking out the likes of Dythen, Deshiel, xenith800, Bosa, Hopeku, Tremulos, Cutting-Christ, DJ Harlock/Cross666, and Dialo. On the other hand, the voice acting is very deadpan and generic.
Content: While it's just a trailer, the direction is a step up from the original, along with the pacing. I can see this being up there with Stick Slayer, Joe Zombie, Madness, Bunnykill, and Keegan's Truck with that kind of direction. That, and your writing is also good.
What's Good:
-Original
-Good animation
-Great direction
-Clever use of imported photography
-Excellent music
What's Bad:
-The voice acting isn't very good
-The fact that this is a trailer
Overall: Here's a nine and I look forward to the first real episode. (4.5/5)
