I just listened to the latest version, and I think what Voda La Void mentioned is what I hear as well - the drums seem to be mostly "sticks on heads" and have little meat or tone, almost as though it's one drum being used. For example, in the change just after 2:00 I can tell that it's kick and snare, but the I hear the kick's beater more than the drum itself, if that makes sense. What are you using for drums?
The tune itself is pretty cool though, I like it. I'm a long time prog fan so this type of thing works for me. I'd like to hear vocals or maybe a lead melody line over the more basic chord change sections, but otherwise the structure itself is nice.
