Great!

Don't worry about the beginning. I think it's good as it is. Infact, you shouldn't change it to anything else, since the way this song shifts from the start to the end could be described as... energizing, in a way.

This song can be used in a flash where people flee in panic and disorder, with the ten riders of the apocalypse chasing them. And halfway throughout the song, people around the main character would die in masses. And right at the end, he/she dies as well. Sorry, my mind got ahead of me. Great song, you should definalty keep at it.
