Can i hear crickets in the background? This song certainly has a nice and relaxed feel but i haven't heard the original so i can't really judge how well it compares. I thought the riffing up until 2:20ish was a little dull. Yes there were some nice melodies but it all seemed a little aimless and i was waiting for it to go somewhere. Of course there's only so much you can do with solo guitar but i still feel it was a little bland. When the chords came in it started to feel a little more structured and i could get into it more. Still though i think a lone guitar strumming chords really doesn't make for the most enthralling music. Have you thought about trying some multitracking? Singing? Percussion?
Just something to add a little more variety to the piece and to allow for more complex structure. As is it remains a failry nice piece that could really do with some filling. It's like a sandwhich with only bread. The bread's nice though. So you just wish there was some ham with it. And tomatoes. hmm and perhaps some salami too...
If you can't sing try getting a buddy to or try multitracking. Good luck!
