The first minute or so seemed a little repetitive. It sounded like you didn't really leave the pentatonic scale or give much space in your phrasing. I really like the guitar around when the vocals first start. Also, at around 2:50 I like that descending arpeggios thing. I think if you just put some simple blues drums in the background, it will sound a lot better.

If you have some time, I'd appreciate a crit back:
