Gonna start by saying this one is my favorite entry out of the Psuedonatural / Outer Planes group, there's a lot of elements in this one that bring it together. Ill start with the beginning with what sounds like stabs of a sakura plugin, that + the eerie wail and pad in the background give off mad Lovecraftian vibes in their subtlety and is a really good opener. Despite what you say about the brass, its actually my favorite part of the track each time it comes in, it really adds a sense of danger to the unnaturalness of the rest of the track and keeps you on your guard. I like how 2:46 and onward you managed to throw melody in there, but by making it half notes you still added a sense of "unnatural" to it as well, smart move.
The only critique I have is the section at 1:03 - 1:53 could use some more work, I feel it doesn't really fit with the rest of the track just in terms of style, its unnatural but its not as atmospheric. If you could fit some atmospheric element's in there it might bridge with the rest of the track better. but in general it stuck out to me while listening.
Overall sick job mate, I get a very cinematic feel with this track and could see it being used as not only a title track, but for a cutscene or scripted/special event in a game. The cinematic feel of it just says its a track that starts a change into unnatural territory and honestly I cant get enough of it. Amazing job dude!
