What are three things that are important to notice when analyzing a work of art?

oh wow this is kind of a personal opinion thing. i think, some thing that shows skill, that can have meaning to a lot of people(or at least some thing that is really cool looking) also some thing that shows inspiration and creativity. for instance i like "starry starry night" but am not a fan of a regular red square in the middle of a white canvas, though both are called art.
