Help describing these styles of paintings?

[Luna]

I have an art test in a few weeks and I am really bad at describing the paintings they give us. We are set to be analysing:
Romanticism
Rococo and
Neo Classicism

What are some general words that can describe each of these styles of paintings which word improve the quality of my answer?
(Like Romanticism - emotional, soft etc)

Thank-you

Romanticism, idilic
Rococo, manierist baroque
Neoclassicism; return to classics
