Keep in mind I haven't read the other comments, so I may be repeating things needlessly...
Some sibilance issues in the beginning.
You know, there's very little going on with the guitars, etc. (which works fine for me, by the way) but for that reason I think I'd like the vox with fewer effects. I like the harmonies, but I'd like less verb and less "sharpness" on that lead vocal.
I like the song a lot. A more natural vocal sound would really serve it well, I think.
