keep it up
I was feelin' the art from the get go. From a design standpoint, you pull together some classic concepts in an original way and pull of a very interesting style.
You still have a lot of room to improve as an animator though. I think you need to put some more time into fine tuning the details. I think you could do well by a few anatomical studies as well. Your characters are cool looking, but anatomy skills always add cool to character designs.
The biggest flaw, and I know it's been said, was the writing. Conceptually, the characters and setting sounds really interesting, the problem is in the delivery:
First off, you never explained why the characters were fighting the giant monster worm. It's not enough to have a cool action scene, you gotta give us a feeling of purpose. On the subject of the opening fight, it wasn't the worst, but it could have been better. I think a major improvement would come if the worm actually seemed like a threat. I know it's fun to make yourcharacters badass, but it's not as fun to watch if there's no sense of risk or urgency. It would have been better if Jazz or one of his counterparts had taken a hit or come close to getting eaten. A victory is only thrilling if the odds are against the hero, otherwise you're just making Dragon Ball Z, and I beleive you can make somthing better than DBZ.
Also, I think you rushed the exposition a bit, give us some time to get to know the characters and the world around them. And try not to introduce story concepts by having a character explain them. Give us examples of the experiences behind these ideas.
I kinda liked the news reporter, but I'm not sure if it was for intended reasons. The juxtaposed homosexual vibe sort of reminded me of Peter Chung's "Aeon Flux." He was a voice of public events, but he was cartoonishly gay, which would not likely be acceptable in our world. Was this a joke or an attempt to paint the character's world in a strange color?
