Very interesting use of a droning sound effect for a piece that sounds calm and ambient. I really love the pads you use, and just the progressions in general. My only suggestion is that there's one note in some of the sections which is off key (you can hear it around 0:13-0:15) which makes some parts of the song feel unsettling, but otherwise I really think this is an amazing work. Keep it up with the beautiful music :)
