Hey man... I think thats a nice take you did. Its not easy to do a single take without slip ups. I can't do it for sure.
Lets see... your playing is pretty fine but you got to note this... like the term, this song is supposed to be very laid back. I can hear you trying to be laid back but there are spots where you lose that feeling. Particularly those with fast runs. Like what my Band IC used to say back in MDC, "everyone, LEAN back!" . And yeah, the music is supposed to give that kind of feeling.. that you are literally leaning back on this big comfortable chair and just letting the music flow. Good work still!
Then the main issue would be your recording quality... its pretty poor man... what did you use? And why don't you convert it to mp3/wma format?
