Truly the best part about this is the atmosphere, so I'll start with that. The mysterious and somewhat creepy vibe this track gives is really nice! You've achieved that with an excellent use of reverb, subbass, and intriguing sounds. Paired along with an awesomely clear master? Yes.
Other great things include the percussion, your sound design (especially the bells at 2:34 and the soundscapes), and of course, mixing and mastering.
Now, my biggest critique: lack of cohesive melody. The guy below me said the same thing, and I'll repeat him. I feel like this track would have been really tied together with an awesome melody. There are plenty of places where I could see melodies fit, like the part at 0:57 and 5:20.
Other complaints include mediocre transitions (the percussion entrance and the transition at 3:36 were quite sudden), lack of chord structure variation, and the inconclusive ending.
Overall, this track has a solid ambient feel to it, and is overall pretty cool! A few minor details need some attention here and there, but I'd say I'm impressed! 4/5
