given the subject of the work, who knows this unfinished skeletal version of your work may work even better ? And if not, the good thing is that with this kind of collaborative work someone else can take it to the next level if it needs it.

Having said that, I understand your point about acceptance and knowing when "done" is "done" and that this isn't always when we think it is. I've kept reworking pieces to ruin before and that's just as bad as leaving underworked. It takes a whole lot of experience to know when to stop and it's one of the indicators of mastery I'd say but no matter how far a creative has come, we all have to wrestle with this all of our creative careers!
Nice post as always Hive account@donnadavisart!
