I must say, the variety of instruments you use is nothing short of impressive and all of them contribute greatly to this being a masterful piece.
The cover art when it's rotating gives a kind of trippy effect by the way! xD
My Prescription: I can understand you went for subtle tones of the main instruments in the piece but they were just a bit soft and hard to hear despite cranking up the volume. Other than that minor thing, this here is fantastic!
Sincerely,
The Doctor
