* This is an official 2017 NGUAC review *
Mm, the epic journey. I love me an epic journey piece. On to specifics...
Mixing, mastering and production: I really don't have too much bad to say here. Great EQing, panning, and volume balancing. Your subtle use of effects really shines in Catalyst - just the right amount of reverb on each instrument. I only would have given higher scores if I was absolutely blown away and pleasantly surprised by bits of production here and there. That's trickier to do in a long piece like this.
I suppose if I had to say one really nitpicky thing, I could have used some more hutzpah from the drums, especially the kick. The way you've mixed and mastered them right now is great in the way that they don't wear on the ears during such a long piece. But they don't stand out much in the bigger sections.
Composition: Super ambitious, and for the most part you pull it off.
The main areas I docked points in were structure and melody. Here I was looking for something to hold on to, to remember, to be catchy, or for some obvious repetition. Ultimately I didn't feel like there was a lot of melody going on. When there's a melody to focus on, what's really happening is it's an aspect of enhancing chords or atmosphere - arpeggiating chords for the most part. There was never a point where a true, strong melody came in (at least for me). And because of that lack of melody, it was somewhat difficult to track the progression of the song. Every section is done excellently, but there's a lot of sections and some of them are different only in subtle ways.
Hope all this helps, and really looking forward to what you come up with for the Knockout Round!
