A critical opinion...

Good kick/snap/clap combo. The melody could use some tightening though. Particularly the bass synth and high-pitched strings synth, which could be tweaked to accompany each other a little better. Nice breakdown starting 1:25. Perhaps some overuse of the splash though. If it were me, I would have used a snare patch with more rasp, but that’s not my primary reservation. I really like the flute melody in the build, but dropping it at 2:50 seems anticlimactic, then reciprocating from that section into a progressively descaled outro seems to rob it in a most subtle way of the all-in payoff that should have happened at 2:50. I would normally give this a 3, but considered the many 0’s anything and everything is subject to, 4 it is.

Production vs. musical merit

What you have here is a mediocre song, but a pinnacle production. The music itself is lacking in diversity, dynamic, and it's almost missing some of the sentient atmosphere in your previous work. It makes for an overall creepy, machine-like feel, but inherent in its dimished sentient atmosphere it is missing a defined character. This is an ideal candidate for an action/shooter game, but short of a given imagery, it doesn't really have its own direction. As for the production, this is some of your best yet. I can see why you think of it as a masterpiece. You've utilized proper gain structuring and eloquently implemented some fundamental mixing techniques, and as a result it sounds very good. Keep this production up, but don't forget to focus on the underlying composition of your work.

Terrible

Please do not take anything contained in this review personally.
I'm not exactly sure what this is. First off, it's in the wrong genre, classical rock is not some kind of experimental ambient psychedelic trip (psychedelic rock would be closer than classical rock, but still a long shot from accurately categorizing this). For that, there is either the Ambient or Misc. genres. The vocals were poorly recorded, executed, and modified. The pad was monotonous, unimaginative, and did not contribute in any way to the song, aside of crude background noise. I percieve no musical merit in this, as the support instrument(s) only use one long note through the whole song. What few lyrics are not inaudible are incoherent. The track clips in several places. The mixing quality is below a point I could have imagined was possible in a song with only two instrumental components. As for its potential commercial music value, I do not believe it has any. This is hardly listenable, and as an artist or producer, I could not possibly construe this to constitute music. I would strongly suggest to review some music theory and take a slightly more commercial approach at songwriting.
