Lovely intro that draws you in, a bit uneasy but pleasing to listen to. Everything really fits together nicely and over the course of the almost 6 minutes the same elements reappear, but it doesn't get boring. A great arrangement of several quite strange melodies and sounds.
The mixing is done really well, so that even with this combination of elements, nothing fells out of place. If I had one critique, I think that some elements could be mixed a bit "tighter", maybe reducing their low end and making them a bit louder and "shine", such as the distorted sound coming in at 3:33 and repeating a few times, or the chords at 2:15, which are a bit too quiet for my taste. But in this genre, I get that this is a tough line to walk, as the effect that I dislike here might be exactly what you intended.
Great work all in all!
