Really cool ambient piece, with so many fitting ideas for the theme at hand. I digged a lot of the things you used, like those percussion steps which provide the rhythm for the track to not only be ambient, which also make me think of a locomotive, like a train (perhaps we are inside a mine?). Also those windy flutey sounds which remind of the wind entering the cave through cracks are fantastic. Great work!

Nice use of delayed/echoed pads to create a sense of space. Bass is nice and menacing.

I love the sampling and sound design. The ominous pulsing. Awesome work.

oh wow this feels like a  spooky wet dark cave. i was expecting it to sound like a dry one from the photo hehe. i like the use of noise in the background "tk tk tk tk chkkkkkkk"
