Interesting song. The first part was alright, but not particularly memorable, but at 3:09, it kicks off into a collage of strange sounds. I'd like if you explored further with the concepts used in 3:09 onwards.

Also, that percussiony-string sound. I want it. Can you send me a sample of it? :P

That was certainly interesting. I CAN say I never heard anything exactly like it before, so that's a definate point in your favor. It's eerie, complex and strange, yet it does have its own kind of surreal beauty in a way.
Great work.
