needs to be a little better polished and a little more in tune. chord progression needs to be a little better presented to the listener. you may wanted to have cleaned up that rhythm line a little bit. a clear beat could really be found at the beginning of the track. otherwise, you have potential to make a great song.
you may want to have slowed it down too, blues typically doesnt flow so fast, and it typically has a more expanded chord progression than just one chord.
anyhow, id like to see what you come up with in the future. keep me posted.
