I don't mind the "back there" vocals so much. It's sounds like you're going for a Depeche Mode type sound.
My critiques:
Vocals - effects and everything are fine, but definitely off pitch in places and it detracts from the overall song. Pitch correct it or re-track and only do one phrase at a time or verse.
Bass - Totally agree with KC.
Guitar - Maybe ease up with the flanger on the guitar. When everything comes I can no longer hear the guitar, just the flange effect.
