Hello there!
I guess I'll start by saying I really like the pitch shift that occurs a ways into the song and continues occasionally throughout. I'm glad to hear it doesn't sound like most other songs that do that in my opinion ;) Also a huge fan of those deep rhythmic sounds. They are nice and loud, but don't overpower the other sounds I think. Only odd thing I heard was a random crackle here and there at the beginning, but no biggie. Nice job! ^_^
