Out of this world harmonies! You should follow that inspiration more! The rest of the song is done well and isn't far from being a Flaming Lips track. Really good job. I think you should do another take of this song, though, it could tighter structurally. By that, I mean you have a good song brimming with fantastic potential right now, but if you just tightened it up more, you could have something REALLY REALLY great on your hands. It could be like a modern version of Lennon's "#9 Dream"! I'm honestly excited by the potential of this track.
Thanks for your comments. I hadn't noticed the '#9 Dream' connection before, but I see what you mean. (the looped backing vocal is actually a sample from a ridiculously obscure Japanese bossa nova song, played backwards!) I've been meaning to do an edited-up version of the song - it will happen in the near future.
