well, a lot of things, really..
the "back" was way too loud compared to the "front", and the end was WAY too abrupt. also, as is my personal prejudice, where was the drumNbass?
I LOVE the music, it's so beautiful.. The only complaint I have is that voice.. I just don't like roboty voices.. If it where a real voice.. that's completely different.. Nonetheless, beautiful electronicy music!!
