Well, what kinda sound/feel were you trying you trying to achieve?
Can't really comment if I don't know what you actually intended.

Technically, you're good enough for this simple piece so you should focus more on the music, less on the playing.
Although, you could work on smoother chord changes.

The softly plucked strings lends some delicacy... has a really folk-ish quality. Makes me think of idling days in a peaceful town. If that's close to what you wanted then it's good but if it was some song about war and destruction...

LOL neither do I.
I think he meant using more jazz-sounding progessions? But that's not how the song is supposed to sound, isn't it.

Anyway about what I said earlier, I guess you can take it as "playing it like you mean it."
But since you didn't mean anything, you can disregard that.
