I tried really hard to find something wrong in the mixing of this track. I shoulnd't have tried.
I especially like how you decided to put emphasis on the vocals using distorsion (or maybe a saturated backing track ?) in the chorus, as it really adds to the power you wanted to convey.
There's just a minor detail that bugs me, that can be heard in the choruses, for example at 2:43. It can be heard every time you say "Ideals born from reasons", at the end of the sentence. I hear some kind of noise there that reminds me of someone knocking an acoustic guitar or something like that (I know, weird comparison), I'm unsure of what it is, maybe the compression that brings in front of the mix the end of the word, or a noise in the background ? I think I wouldn't have noticed if it wasn't repeating each time in the chorus, but it's maybe just... you know, me being myself and seeing problems when there is none. xD
Well, maybe there's actually a little bit too much compression at times, but this is coming from someone who just spent two weeks mixing orchestral stuff with instruments that needed a lot of room to breathe - so I'm most probably just biased on that point.
In terms of composition, I thought, at first, that there wasn't a lot of originality (maybe because of the first chords of the chorus ?) although the track is still very efficient, but the magic is actually more in the details. The sound design/instrumentation on the melody that starts at 0:28, the last seconds of the chorus, the small risks you decided to take in the solo section of the track, it actually all adds up to create something that sounds familiar, yet has its own identity.
In terms of pace and structure, I believe you wanted to create a contrast between anger (chorus) and despair (verses), but the guitar of the chorus tends, in my opinion, to evoke determination more than anger, and the power of the vocals in what I'd call the "despair" section constrasts with this interpretation as well, so I'm not sure I got your intention right on this part - but once again, this is coming from someone used to work with different styles of music, with a different problematic. :p
