Wow... This was wow. I like it. LOVE it.
This was soft and serene, but it had enough of an uppity beat to keep it in that "active" zone, y'know? Where it's subtly engaging and doesn't get boring. That uppity beat came and went, which worked really nice.
Maybe it's just my taste, but near the end (around 3:00, more precisely), that chorus was just a little iffy. It came unexpectedly, but I did start liking it within two seconds... Maybe that part would've sounded easier if the chorus were a little softer and "distant" in the background, instead of the focus being placed there? Unless that part's important to your heart in the music, of course, and it still sounded nice as it was :)
Overall, nice song! I don't have a reason to rate this anything but a solid 5.

I imagined being stuck between space and heaven. Very relaxing and enjoyable. Keep it up.
