This is really a new direction! Nice work.
If I were to psychoanalyze you based on your songs, I would say that the only thing you really need to work on is your sense of melody. Like, you can (and do) write great melodies, but you also write melodies that kinda just wander around. Your songs are best when they're totally insane because the insanity and things happening all the time kind of disguise this fact. I dunno, I'm kind of hypocritical because I have the same problem :D
And honestly in this song I don't really feel like the melodies are speaking to me until about 2:06. After 2:06 it's awesome, but it makes me wonder what the purpose was of the first half the song haha.
I really love the music box at the end. It really is a beautiful chord progression/melody, and breaking it down to its essence really adds a lot in my opinion. Though I needed to listen to it a lot to really understand what the melody was doing. This might be my own fault, but I think it may also be a problem of dynamics.
Anyway don't let my crazy nit picking get you down cuz you're still one of the best musicians around. Keep it up.
