I liked it a lot just like it is. I guess I disagree with CD on this listen, I thought the wide spectrum on the guitars really set off the vocals, I liked the male vocal coming in over the female vocals.
My only change would be to bring the vocals out a little more as the build progresses so by the end of the song, the vocals are still 60% of the mix. I think they get a little overwhelmed there towards the end by the instruments.
Nice tune, though, and great arrangement and production on the song.
