The music is great.
But don't take any offence from what I am about to say;
It's kind of desturbing when people are talking about massive bloodbath and a bunch of zombie rushing out of a building or something like that, but I can still understand you feel when you think of music that way: You try to paint a picture of what you're hearing. I can't blame you for that, I do it all the time. And most people do. I'm just saying. A LOT of people describe their songs with the feeling of being attacked by a crowd of bloodthirsty zombies.
But on another topic, great job. I felt a bit thrilled when I listened to this.
OH SHIT A ZOMBIE!
Keep up the good work!
