What do these terms mean?

So I watched this video; https://www.youtube.com/watch?v=CB44zABOeXI

I'm not that into literature or writing comparisons, but I thought it was kind of interesting, but I'm not sure what most of these terms actually mean lol, could someone explain them for me? (I get the general idea of the main category things, but I'm a bit unsure what is meant by the sub-categories like "depth - hidden aspects" for example.
