Some things I would not do.
Take a lok at this: https://www.youtube.com/watch?v=lNI07egoefc
Now, what to really do.
Take a posture, for example How a specific technique affects the expression, or How an ideological thrend demands a new perspective, like Futurism.
And convert that knoledge into some specific. For example the hierarchy of the character were defined by it's size in old Egyptian paintings. That is the same as when we define the character's size on a movie poster.
Note. I am not saying what "art" is good or not. I am telling that you need to develop a posture on the subject.
There are some very specific topics that you can apply directly.
For example how trhu history some symbols or colors remain or evolve in the meaning, lighting in painting, etc.
Or the most basic and direct. The style of the image, the level of abstraction; the look.
