You sampled Requiem for a Dream?
I just find that odd...
Evidently, I think you could go crazy with the percussion of you chose to, if done right that could add to it. Its repetitive, I recommend using the louder chorus to help with that in some areas.
I'm kinda 50:50 on adding glitch music would be good for this. The intro is kinda long, I think you should shorten it a bit around the repeating chorus.
This kinda sounds like a different version of Requiem of Dream. Parts of it do anyway. some of the highs (one of the tail ends? When equing, the sounds that makes it sound high.) should come down some, like on the crash.
Keep it up.
word thanks man!
