The recording is missing some high frequencies. I would recommend using a microphone that is positioned at the 12th fret of the guitar and aimed at the sound hole. experiment with the mic position around the guitar for it is very determinant of the sound and frequency spectrum
Thanks for making a contribution. I really, really wanted to use some of the sounds you recorded, but the background noise was well beyond what I can suppress with background suppression filters and still get a clean sound. If you can re-record with lower background noise and a better mic, you've got yourself a winner.
