The soft background loop was engaging, from beginning to end. This combined with the tambourine, or some other instrument you have in there, has a great start with the beat while not overpowering the rest of the orchestrations. The combination of percussion and soft string instruments give off a sense of balance that is obtained while listening to this piece.
It doesn't stay on the same line continually as a trance piece, so it adds a polite amount of variety to the mix. One of your great musical creations indeed. Keep it up!
