Because you asked for one :P
Here is your review:
There are very few things that could be improved with this song, and I think perhaps the very beginning area of the intro could be rewritten a bit (maybe the first thirty seconds?) It sounds a bit too complacent for the energy that comes later from that nice bassline that kicks in around the first minute and becomes the real theme of the song.
However, I really liked the spacing of the theme breaks (for instance, the one around 2 minutes really helped with keeping the song fresh), as well as the high pitched bell-ish sounding instrument used during them. Really lends the song a kind of fresh start every time, which I really think helps to keep me interested in listening to the whole thing (as you said, long tracks take a lot out of you :p)
Barely any room for improvement, 9/10, 5/5, DL'd.
