First off, while I really like the piano part at the beginning, it doesn't really feel appropriate to me. I think you'd have a much greater impact if you cut that and started with the choir hit. Speaking of the choir, I honestly have no idea what the lyrics are or are supposed to be, but it sounds like they're singing "Suck my dick." Not even kidding, that's just what it sounds like. The orchestral part is powerful and I like the triplet rhythm. The B section with the strings is beautiful and well thought out in terms of the pizzicato support section. I do think that you loop the last string part a few times too many for it to have any meaning.
Really cool, dramatic piece.
