This is really cool. The effects at the beginning had me believing that it was going to be a really generic spooky halloween song, but when the 8bit stuff starting rolling in, I was mistaken. You have really unique compositional methods, but I think you can use more unique sounds. The sounds you used were fine, but they just didn't leave an impression. I really like it though. The mixing is quite good, much better than I can accomplish. Happy Halloween!
