1st Listen:
Nice calm vibe. I like the stuttered voices. There's a moment at 3:06 that feels really special... great work.
Some of the ambient textures at the end feel like they point to a next track.. like this is one sentence in a paragraph. Maybe that's the arrangement recapitulating earlier themes in its own way... regardless, it's well done.
2nd Listen:
Some sounds at 1:03 made me take my headphones off.. I thought someone was knocking on a door somewhere. I'm not sure the musical statement you intended with them... if that's a style / artistic voice thing, keep it.
3rd Listen:
When you master this, I hope the details really shine through... the beginning & end sound like they'll be rich with layers.
