It happens all the time. You start with a drawing, a painting, maybe even a written work. It’s good, but you think it could be better. So, you take some time to look it over and think of the ways you might be able to improve on its various elements. Then unsatisfied you change, recolor and edit, until the unique creation you had made is barely recognizable.
It could be that the modifications actually enhance the piece. However if you weren’t careful and tried to change too much or kept tweaking the same element in an effort to obtain perfection then it’s quite possible that what you’ve actually made is a mess. Its times like this, you need to learn to leave well enough alone.
