Soothing...calm...that kind of feeling.
Haha, the length doesn't matter--if you make a longer version, the sound will still sound lovely.
At first I wasn't sure about the kicks, but it keeps the ambient sounds from wandering too far by giving it some time and direction.
And I really, really like the serene mood I feel from this. A calm, beautiful, sound...focused, yet delirious and mesmerizing feel to it.
You know, I've listened to several of your pieces and I really like your style. I just had to blurt that, haha :P
And for the collab, I shall watch.
