Very nice ambiant album, liked all the textures you crafted , works well with the little explanation you came up with , good job !

Track 1 definitely sounds like it's meant for the factory.

Really cool soundscapes.

I feel like some of the upper tones are a bit on the harsh side and a bit too forwards, like there could be a bit more tonal balance to make it easier on the ears. 

That tremolo work on the last track is really sweet. That one is definitely my favorite.

Fantastic work!

Really, really rich soundscapes you got here, I love all the textures and variety you got for the ambience, really threads it all together well. I'd say the fourth track is my favourite of the bunch because I felt it progressed a bit more musically than the others and had a bit more to it.

This track, I'd say, works perfectly for some kind of game OST. The first three tracks really sound to me like just plain ambient background music for different areas/scenes; they each had a different feel: enchanting/mystique, the uncovering of something, very tense/sinister. And I think that this track, overall conveys a story very well, and immerses you into the space that you've crafted musically. (I will note I think you crossed over the max runtime a smidge, but it's fine)

Really enjoyed listening to this track! Great work! 

Lots and lots of sounds here goodness. Your last track is the best. The other three were good, but to be honest, a bit boring. Nothing really happened in them. They were to reparative for my taste. In any case, it was still a very good submission! I hear and feel what you were going for. You had good mixing and balancing which is never an easy task. Good work here!
