As a fan of this style of dubstep in particular, it's honestly insane how good this is.
Outside of the drop sections, the arrangement is very enjoyable to listen to, with a lot of variation (also the sound design is really good). However, and this might be somewhat a style thing (and it's entirely opinion), but having listened to it two or three times now I still can't really recall the melody. (To briefly use the comparison to Xtrullor in the description, the melody in tracks like Paracosm and Cry is typically very memorable even after one or two listens.) There almost doesn't seem to be a lot in the way of melody, as far as I can tell. Ultimately there's nothing wrong with this, but it does mean the track has less identity than it perhaps could.
The arrangement in the drop sections is excellent. Enough variation to keep the drop feeling fresh, and the difference between the two drops is also enough to feel fresh. I will say that it seems a little odd to me that the dubstep bass seems to remain at exactly the same volume during the sections of the drop where the vocal chops play - the dubstep bass seems to drown out the vocal chops a bit - but this is again likely just a personal opinion and it doesn't negatively impact my enjoyment of the track.
The sound design is extremely good. I don't have much more to say on that front.
5/5, will listen to again.
