Minimalistic, in a good way!
Calm and slow paced, slightly eerie and ethereal but not too spooky. I think the title is fitting. I like the instruments used here, sounds like some kind of ice bell and a koto. Not much variation, but makes for some decent BGM. I would like to see you experiment further with those instruments in another piece. I also like the wave sounds in the background, makes the song more soothing.
