I like the dark mood at the beginning. The part at :18 hits hard. The distorted vocals at :36 are cool, and somewhat morbid. I love the intensity, although the piece is a little slow to develop. After around 1:30, I think you’ve overdone it a bit with the angry vocals. It seemed nice and climactic up to that point, and I was itching for some melodic content. At 2:35, you seem to switch up the beat a bit and try to take the piece in a different direction structurally, but I think the piece needs a little structural relief at this point. The vocals also cut off pretty suddenly at 4:12, as do the guitars at 4:31. I think you need to give this piece a little more shape. The experimental texture is really cool, but without any instrumental variety I don’t think it can function very well as a stand-alone piece. One thing I do like about the piece is that I can hear everything in the mix clearly throughout. There are a lot of neat ideas here, but I think the arrangement needs some cleaning up here. Keep at it, man!
