This is wonderful! I love the ambient genre in general, and this is some damn good ambient music o.O
To begin with, the panning is great. I also like the fact that you're not afraid to use very bright sounds (+ points for not making them headache inducing!!).
The talking and other IRL sounds are a nice touch, and gives this track a real movie vibe. It also shows how well you managed to mix this.
The sound that plays through the entire track that sounds like a clock that ticks too fast is brilliant. It gives the sense that time is ticking away very quickly somehow, even if this is a slower track in general, with a sad touch.
I really get the "someone lying in a hospital" sense from this music, for whatever reason (even if you didn't use that heart monitor sound). I guess that the vibe is just similar; you're kinda waiting for something to happen, seemingly powerless to affect the outcome.
I know that the story is different than that though, from both the title, the talking and the "mistakes" and the description though. I'm just saying everything that comes to mind. I guess that in general, this also evokes the "too late", "the worst imaginable thing has already happened" vibe, if you know what I mean, which is more in line with the story XD
The vibrato strings are also cool; as I already said, nice panning work in this track. The static is of course cool too, as are the footsteps here and there.
I love the robotic sound in the ending, especially as it seems to be saying "mistakes", a few times (maybe something else before that?). I knew that the ticking would stop during the last seconds. It's pretty perfect. I think I would've made it tick as loud as possible at the very end right before stopping, and really letting the reberb that is left be heard for a while. You did make it louder, which is nice, but I think the effect could be even more dramatic (without overdoing it, of course).
Without the talking and other recorded sounds, this could also fit perfectly as background music for certain kinds of games. Of course, this track is telling a story almost as a timeline. But it would not be difficult to make this loop (not saying you should though, just a speculation), and even more, it could give the sense that the player is stuck in a loop that they can't affect.
I always love atmospheric music, and this sure is some great atmospheric music. I think you could definitely become a movie soundtrack composer, with your ability of storytelling, and attention to detail.
Absolutely wonderful work with this in general. I don't really have any criticism, as I think this track really conveys what it's supposed to quite well, while everything sounds good. Keep up the awesome work!
P.S. Is that a rocking chair close to the end, like at 4:42?
