As far as arrangement goes....for the first 40 seconds there isn't much to pull you in. After the long beginning...the vocal should take over but it's too far back in the mix to do it. As a bed...it's going to be hard to stick stuff in between that guitar. It's a wall of sound. I'd use that rhythm throughout the song but I'd also find a couple of more ways to present that guitar, the others being far more sparse....to give you room to arrange some room for more different sounds.
I like the vibe of this though...a lot more could be done with this.
