The song is lovely, and your version is expertly played. The guitar playing is exquisite.
I concur with the above comment that the mix sounds a bit disjointed. I feel like I'm hearing the guitar from across the room, but you are singing into my ear.
I'm not sure exactly how to fix that, other than retracking the vocal and standing farther from the mike. You might first try rolling off the very high frequencies (>8K) and doing a notch cut on the very lows (around 100K). That might help diminish the proximity effect.
Also agree that the rain effect isn't quite right. I like the idea, but that particular sample sounds a bit weird.
