I'm not much into things that are just trailers. I did think this was fairly good. It had nothing to do with Halloween, though. It was just fun to see your new art style. You really do have potential. I am familiar with the Channel Federator logo.
So many people have worked with it that it's hard not to take note of. You should have made it longer. Even a trailer should have more for it. It was still pretty good. You can do better.
