First I quite liked the overall song. Listened twice and really can't find an issue with the vocals they fit the song really well.
As far as constructive feedback I like the way you sing the 3rd last line sounds on each verse - perhaps if you swapped the melody of the 3rd last with the last line for more of a build up?
The song has a nice folk feel - perhaps an hammond organ rather than the electric guitar? (purely a matter of taste).
Anyway I've now heard it 3 times and it is growing on me.
