Four Green Fields:

Your voice is stronger on this song and comes across very well. I really love your tonal quality.   
Technically, the guitar could be a little louder, and there is still some sort of hum that masks the song a little.    Closing the shades would probably improve the video quality too, even if you had to use some interior lighting; try for something less directional.
On this video towards the last 1/3 there is also a video-sound synchronization problem. DK what caused that.
I must say that I love the emotional connection to the song in the last verse(s) and your phrasing and delivery to tell the story. Very well done.
