If you post a picture on social media, and it doesn’t conform to the traditional rules of art and composition, you can expect to be challenged by the Paul Blart Mall Cops of Art. They can be merciless. But I want to let you know a secret. These people don’t buy pictures. They don’t publish pictures. They just critique pictures. Publishers, editors and art buyers may not care about the rules – if you come up with something that is striking.
