Congratulations on the full release, there's a lot of improvement since I last heard your output. I'm glad you were finally able to get the hang of mixing to the point everything is well balanced and audible. I've only one complaint, the drums lack presence and do feel, eh, drum machiney, due to the sound or how Superior Drummer's samples work, idk my dude, something about them feels dead, I'd recommend experimentation with some other drum plugins if you can find the time and money to get them (I'd advocate for piracy but uh, yeah). I'd recommend Ugritone's stuff as I've been having good results with them, and a few plugs might be up your alley. The rest are nitpicks really, guitars bite too much and don't bark as much as they should considering the mid 80's 'tallica sound you're going for, I'd recommend a TS boost (tone at center, level dimed, gain at 0) setup before distortion/amp to tighten up your mids and give it more of a presence. Cymbals could also be a smidge higher, but that's just me.
Compositionally a very victorious feeling piece, lots of callbacks to To Live is To Die. I'm sure it's due to being the last piece done, it does feel like the end of a journey. Good show lad.
