I've looked at all of your work here, and this is your best tune. Excellent work. While slightly disorienting, it is captivating and strongly mood generating. Good balance of bass/treble. The melody progresses but remains passive which is very important for background music. The only thing I dislike is the slow down at the end of the track, as it's too powerful a distraction. Consider a partial fade out instead, and ending with the reverse drum you are using 0:20, and echoing into silence.
