It's an interesting obviously spacey, atmospheric track that offers quite some powerful visuals and a good degree of depth as a whole.
I don't really understand why you repeated the first two minutes again, especially since the build-up was already quite lengthy and then it seemed as if you only needed an "explosion" of sounds and a climax. I think it could have worked better if you either kept the repetition and added a powerful climax at the end before fading into darkness, or scratched the whole repetition and introduced more instruments and variations on the theme starting from that sort of breakdown.
I mean, don't get me wrong, what you did wasn't bad at all, but it honestly felt kind of like a lazy move when your song already had a very solid atmosphere and structure you could have built upon. Other than that, I think more background sounds would have helped the section at 1:34 - 2:01, maybe a background arp or rhythmic synths perhaps with a driving bass line.
Overall, you did a good job with your ambiance and I think you made justice to the artwork of choice.
