Impressive...
Uber-professional. You certainly have a knack for this. The flow and pace of the song is just excellent...I would have preferred some really kickin drums at about 3:30 to really drive the song forward and build up the energy - but the way it sits is still fine and why I'm not giving this a 10. Some obviously very complicated and probably modular fx arrangements to achieve the huge ambiance in the song.
Reminds of a much more relaxed BT.
