Would have liked to see a bit more for opening the story up, feels like a super sneak peak of a trailer. Like others had said, text is uncomfortable to read, and definitely need a mute button option. I don't think the music adds anything to the comic, just feels like it's there for the sake of it.
Some of the motion didn't really work for me either. If you are going make a flash comic, how much motion inside of the frames instead of just moving the pages around? That would be nice, wouldn't have to be all out animation, just some motion. You could add sound but only where it's going to add something to the immersion.
Good luck.
