Whoa snap.
I like this alot, it pregresses PERFECTLY, really picks up towards the end, and then fades slowly into an ominous nothingness.
I agree with the guy below me, the intro was dragged on a bit, but honestly, what trance song isn't? :P Plus you threw in enough variation to make it worth hearing.
All your transistions were flawless. there weren't really times when things were just BAM! there. It all slowly fades in until you notice, "Hey theres strings over here!" and "Oh look, a shaker in the right headphone!"
It all came together seamlessly, well done.
