Needs serious work.
I like the music a lot. Good choice on that. And now here comes the bad part.
This makes no sense whatsoever. Marginally more sense when I read the explanation in your comments, but if you have to retroactively explain what is happening in your video then you aren't telling the story properly. Who are these characters and why am I supposed to care about them? This may make sense to you but you haven't explained a thing to us, the viewers, and if you only made this for yourself there's not much point submitting it to Newgrounds for others to view.
You mention in your comments that you understand, at least on some level, that these 'slow parts' seriously drag out the length of the video. I need to reiterate this, though: The slow pan at the beginning -seriously- drags on. Far, far longer than is acceptable.
When the character disappears into the growing white burst, toward the end, rotating the image like that calls unnecessary attention to the static nature of your drawings and breaks the drama you at least seem to be shooting for. It might have worked better to shrink, darken and fade, or something similar. In some ways, letting a still drawing remain perfectly still seems less static than having it move without actually animating.
