It wasn't one of my favorite songs, but it was still pretty good. I think it's because it gets a bit too redundant. I still appreciate all the work that was put into it. You should have put the animated video up here! Or maybe, it wasn't appropriate for this website or something. I can hear the drums well.
I do think this had a good length. As it wasn't that well detailed, it shouldn't be too long. Again, that's kind of a disadvantage. I guess I'm not as big a fan of heavy metal as I thought I was. I would still recommend this, though.
