Pretty good, man, it's got some potential. I think you just need to incorporate a few more progressions into the mix if you want to avoid those "Knocking On Heaven's Door" comparisons! ;) At first I thought the rhythm guitar made a few fumbles on the timing, but those little pauses turned out to be quite effective for the feel of the piece, so don't worry about 'em!
Well done, and keep working on it - it could turn into something really good.
