romantic-victorian-age - Question and answers

I'm a graduate student focusing on 19th-century English literature, and I've selected poems by John Keats (Romantic) and Matthew Arnold (Victorian) for my analysis. I've read critical essays, but I'm struggling to structure my comparison in a way that's clear for my audience. Specifically, I need help on how to contrast their approaches to themes like nature and industrialization without oversimplifying. I've tried creating charts, but they feel too abstract.
