I've changed around significant parts of my tunes based on what I'm hearing when I listen back to my recording.
I think it's valuable to do this as soon as you feel you are ready and pretty confident of what you're working on. As has been said, you can go at it again and then again as you hear what you're producing and want to refine tone, pace, chords, etc. to match with your goals.
Also, for a well produced recorded sound, there are techniques to learn beyond just playing well. Controlling your breathing, finger squeaks (or lack of), smooth chord changes while fretting, consistent tempo, string choice, etc. are all things you learn about while recording your music and then evaluating your results.
