Have to agree with Lynn, the vocals sound fine "as is". Maybe you could back off the verb on the instruments at the beginning, as my first thought as the song started was " this is too wet".
It got less obtrusive as the song progressed and everything came together, but then I thought the same thing as the song ended and I wanted a little more definition as the sound got pared back in the last few bars.
This is a really, really good song. I like it a lot.
