It sounds like you double tracked it and that's about it to me. I have this on a CD of some stuff from the clinic. I really enjoy listening to this (along with a shamless plug for Chris Harris in your thread. Sorry).
Cool, i like it. Dont see anything wrong with guitar effects or that atall. (slow phaser?) Its lacking room ambience in my ears. It would sound brilliant if you used a good mid sized ambient room with some extra mics placed farther away) But thats just me nit picking. Sound good man.
