Really, really nice song! It sounds great through my headphones and high frequency hearing loss, so take the other folks vox eq (voice equalization) advice - I can't really judge.
Only two things really bother me
The D# to D chords in the intro, after the first verse, and before the last verse/outro contain dead space between and after them without even the sense of room ambience in there. They need something to give a feeling of continuity in there (except possibly the ones in the intro could stand as is.) The same progression in the bridge works fine because of the chorus effect behind it.
The other is the "instrument" break - that is really a hokey sound. Personally, I think a flute-like sound with the same "airy" quality the song has would be perfect.
Just my simple-shit opinion. I really like the song.
