Pretty good.
You've got some good ideas here. Your animation is pretty good and the music that you do have fits what's going on rather well. The only real problems I have with this so far is your subtitles and the intro... and the non-flowing way your capes are drawn and the mouths move. All in all, I think you've got a solid base to build on since you've obviously put quite a bit of work into this. If you want a little more detailed of a response, figure out a way to get ahold of me and I'd be happy to help you along by tossing a few pointers to you here and there. I'd like to see a completed version of this sometime, so don't give up even if this gets blammed.
