Amazing use of foley on the track, not as easy as it seems to pull of.
Some instruments imaging could be improved in the mix.
I could see this for the begining of a cutscene, I do fear that the foley is too essential to the track, not just texturing the sound, so as an amb track for a game it could not work as well, other than a intro cutscene to something.
Even the ending of the piece sugests it almost as an "intro"to something else.
But I see you went for more of storytelling approach, I do love that!
Good job, take care :)
