I noticed several hesitations, as did others. I actually thought you might have recorded it in one take, as it's something that happens to me if I'm not really completely comfortable with the song. One is worrying about the next lyric and you get stumble in tempo, or the movement to the next chord doesn't hit. My bad habit is speeding up when I hit the record button. I don't do well with a click, but if I can put a simple midi drum track, just a thump pop, thump pop, I can lock on to that better than click click. Then dump the drum track.. .it's just for timing purposes.
I think that given the quality of guitar that you have, I would definitely look at getting a microphone. A good small condenser mic is well suited to recording acoustic guitar. You might also just try using your vocal mic. I've used the same mic for both before. It's all about finding the right position.
You might also record both direct and with the mic. It's not like you're limited in the number of tracks, or that it will cost you anything (assuming you have an interface with two inputs). Then pick the better sounding track for the mix.
Keep at it, the more you do it, the better you get. And the most important thing... have fun doing it.
