I'm not a pro, so I can't say there's much to improve. This song is great. I may just say it isn't as "dynamic" as the tags say. Pretty slow, it makes me think of something between blues and folk. It's great. I mean, I've never heard this kind of music here. And I pretty much like it.
So... I can't see anything to improve here. This song is really great. Again, I'm not a pro.
