Where does photographic analysis begin?

Hello, this movie friend. I want to ask a few questions after seeing this movie, also for studying together.

First, the exposure position is wrong, that is, the problem of metering point, which is a common problem for newcomers.

Second, the theme is not clear, and the shooting is more casual.

Third, strengthen the basic exercise of photography, and read more books and masterpieces about composition!

Learning to read histograms is helpful for your photography.

If I am wrong, please forgive me!
