Hey man!
This track is awesome, never heard anything like this before! Great style... I don't think that this atmospheric style of music needs some kind of drop, it is beautifully composed and very harmonious. If you'd wanted to change the track up a bit, i'd simply mute the drums at a few sections (for example from 3:18 to 3:22, so the bass hits again at the high note, a "b" i believe)
Great piece of work though, would love to hear more from you!
