What are you using for drums? (I've been looking for software to do such) The vocals sound very Interpol. Not a bad track. I do think there is a little disconnect between the power of the vocals and the softness of the melody instruments, though. The cadence of the vocal line doesn't seem to match. I think a dreamy vocal line would work a little better. Feels like more of a gap to my ear than musical space.
EDIT: I'm hearing a little Postal Service to the music.
