I find the elements you used to be very pleasant to listen to: the arpeggios, wind, water sounds, etc. For the most part I think you captured frozen landscapes. I'd say I don't feel a "stillness" as much. This piece does feel like it belongs to a snow level. It's not in your face but it definitely isn't a pure background piece.
On headphones I notice a low distorted buzzing sounds throughout on the left. I am not sure if this is intentional but it feels like it takes away from the clean, frozen sound you are going for.
Very lovely piece! I listened to it a few times. Great job! :)
