The Mona Lisa, the most recognizable painting in the world, isn’t perfect. In fact, many artist (and computers) today could copy it and change it to make it better from a technical stand point.
Yet, no one cares about making the Mona Lisa better. We care about the story, the emotion it evokes.
Here’s the thing about art:
Art is never finished. It is never perfect. It is shipped. It is displayed for the audience to enjoy.
So, of course, now that it is done, we can make it better. Perhaps, that is what you want to do. Create a 2.0 version. But that is for another artist with a blank canvas to decide.
