Okay...
This was pretty good. Looks like you put a decent amount of time and effort into it. It's major fault however is the first few seconds. You shouldn't have silence in the beginning. I don't know how to explain it, but it bothered me. Either have the music start earlier, or have a sound effect in there. The rumbling effect was great, but needed sound. The text that slid across the screen went WAY to fast for anyone to read. You did very well with the rest of it, I think one last thing that needs to be worked on are the cloaks you have flapping in the wind. One is in the preloader, the other is during the flash. You should make them smoother, because the rest of your flash is very smoothly done, and it should fit in better.
-Good Job-
