@literally45-- It can be difficult to recognize romanticism without being familiar with the earlier trends in art, especially art during the classic period.
I can't say that I'm an expert on romanticism art but from what I know about the ideals and worldviews of the movement, I assume that it's less about rules and perfection and more about natural, imperfect and even exaggeration.
You see, the classic period was about logic, concrete ideas, perfection, order and use of intellect. Classical movement leaders felt that anything could be explained with logic and there was a desire to fit pre-existing structures and ideals. It was about rules. Romanticism emerged in opposition of this movement and argued that emotions, spirituality and instincts can help us find the truth. It was a much more individualistic movement where people were encouraged to appreciate and love themselves and the world just as it was, without trying to fit in or be perfect.
I think this gives a good idea of what romanticism art looks like.
