It's a cool song, I really liked the intro. That vocal, though, is jarring. I agree with below (except with it being a choir, it sounds like one person), it needs reverb. In addition, may I suggest breathing points? That could add towards the sound and make it less jarring and maybe more realistic. If you were going for a choir, then I'd try adding several vocal layers either detuned a bit (never tried this, may be painstakingly unbearable) or have chords be sung out.
I really like what you did with the noise in the beginning, making it sporadic and almost like a high-hat. The ending isn't too bad, but maybe changing the notes that the guitar is playing for the fade-out to make it seem more melodic. That's what I would do if I could, but it's your song, and you may like it like that. Different tastes and whatnot.
Overall, this song is nice to listen to. It's a cool-sounding track, but I would like to hear that voice become less jarring.
