Call me a traditionalist, but I found the doubled vocal to be very distracting. I want the vocal to be hitting me in the forehead for the majority of a song, and if you want to double it for effect here and there, thats fine. I would much prefer to hear the instrumentation spread out through the stereo spectrum. Try doubling the guitar instead of the vocals. Then add a 10 ms delay to one side to get a psuedo stereo effect, or just double track them. Also try panning some of the secondary instruments (xylophone or piano) slightly off center left or right. Bass, snare, and kick (more volume) need to stay dead center though. I could get a much better sense of the instrumental mix if it was spread out a little. I think there are some good sounds here, but its just hard to separate them with the panning that way.
Obviously the vocal isn't perfect, but I think the doubling magnified the problems. If you just used a single track dead center, then you could use autotune to nudge the melody in the right direction. If you really want to double the vocal, I wouldn't hard pan them.... as I said, lead vocals anything but dead center drives me nuts. That doesn't mean that a harmony part can't be panned though.
I think there is some potential here, and I would love to hear an updated version.
