While I love harmony, I can also completely lose myself in dissonance.
Did you not win 1st or 2nd place with "The Place of a Skull" back in 2014? In the very least, I recall you earning a high placement. I hope the judges don't discriminate on genre or approach alone! That said, I understand why a piece like this might be difficult to judge. The mix sure is effective, as is the structure. For instance, I like the sudden silences here and there, and then the quick (almost) slashes of and hammerings on the strokes to grab the listener's attention. The buildups, like the one near the end, are also most effective.
I've heard the piece you're referring to a fair amount of times, and I think it'd be fair to say you managed to channel the structural elements of it quite adequately. Not implying you'd directly have taken anything but inspiration from it, ofc :p
Also, can we talk about the fact that the artpiece was essentially posted yesterday, if I'm not mistaken? So you must've gone full throttle with the creative process here!
In short, I really enjoyed the listen, and I suspect I shall relive and possibly indulge in that enjoyment some more, a bit later ;]
Btw, gotta love that commentary on the titling process.
