Now you are getting there, with the recording stuff that is.
The voice and guitar always had the potential, nice relaxed sound.
So now you have to get nit-picky.
Watch your endings on the recording, your guitar has a lovely looong decay that you don't want to clip the end off, count to 5 or even longer and then turn off the machine. If you still have lost a bit do a short fadeout over the last second or two.
IF you want more perfection, try working with a "click track" it's like a metronome and would keep you bang on the timing (that is unless you ignore it sometimes, which I know I do)
Keep it up, JohnB.
