Yeah, you can hear the nervousness in your voice a little at times, which is very natural. You seem to get more comfortable during the second half of the song, which sounds very good. I don't think I noticed many, if any, mistakes on the guitar. Maybe 1 or 2 small, but barely noticeable things, and even then, you have to really be listening to catch them. Good work overall though. With more experience playing in front of people, your comfort level will only increase, so keep it up, and don't shy away from opportunities to play in front of others, no matter how nervous you get.
