Good, but some issues.
i personally found it a bit slow overall until halfway, when it gets to that point you think it's another bit of music, the "choirlike" (not sure what to call them) drowned a lot out and made it seem too much like a trance track, when it speeds up you think it's going to keep that speed for the rest of the track, but it slows down into the same sort of, mush before.
All in all i think it's pretty good, but a little slow to start, then it doesn't go anywhere.
