i would say 8/10 for first try quality is not bad at all. I think you messed up on the intro you need to stay on the Am for 2 more strums, but not positive... as For the singing it was in time and key the whole way, but it needs for feeling. Good job overall!

Not bad. It was pretty good, although te very beginning chord chages are a little sketchy.

7.5/10. nice job.
And if ever You come near, I will hold up high a mirror.
Lord, I could never show you anything as beautiful as You.
