What you're saying does make sense BUT for example you were explaining say... sequential artists, such as, dunno, Manet and Van Gough, you could explain what drove Impressionism, and then what Post Impressionism revolted against. Then you could talk about personal stuff and subject matter. Or even Deschamps and Dali, with Dada and Surrealism
Just because, I dunno... say if you were to do two abstract expressionists, let's say Kandinsky and Pollock, several of the points would be similar. Just like if you were to grab Botticelli and Michaelangelo: they're different parts of the renaissance and you wouldn't be able to compare them too much unless you remembered that one was better at anatomy and the other was better at form (or something, I've forgotten)
I think it's because Frida and Bacon are different movements?
From what I know, Frida is "Feminist (Modern)" and Bacon was like... I THINK expressionist? I can't quite think of what to call his style, but he's also a modern painter too, isn't he?.
To be honest... Let's just do what we're comfortable with. It's possible to do well, as long as we know our stuff
