Any artist will tell you that there always seems to be one more thing that will make his creation a bit better, hopefully perfect.
But there does come a point when he'll admit that it's time for completion. It's time to declare it finished.
Below is a picture of my latest completed sculpture. It's still in clay and will need to be cast in plaster so that I can attempt a clay duplicate of the original. Then it must dry and be fired twice.

But at least this phase is completed.
