How to evaluate a good photographic work

From a good photographic work, you should be able to see its central idea. If most people can't understand that work, it is a failure. If everyone can understand its central idea, it is a good work. From the perspective of photography, composition, exposure and color are all essential. In addition, if the central idea is more prominent, even if the composition is not good and the color is not good, it is also a good work. To put it bluntly, it is still your first feeling when you look at this work.
