Very nice piece. Relaxing and emotive. You're creating a really interesting soundscape here. I like the low-tuned 80s snare.
I don't know about those hats though, they sound a bit too disjointed from the rest of the piece. As if they are on top of the actual track.
Also, I'd normalize the entire track before submitting it. By normalizing, nothing gets lost, it just literally becomes as loud as it can get without clipping or distorting.
But yeah it's a nice piece. Idk if this would work in a game with the voice samples around 2:38, but on it's own it really works as one of those tracks that you would put on and just get lost in thoughts with.
