I think you have gotten all the literal images, although you have not specified what types they are. I won't attempt to classify them, since you haven't asked for that in your question. However, I hope you intend to do this if you are writing a paper. Obviously the chilled white wine, blue cheese, crackers and pears are gustatory images, and the pear skins are also visual images.

I think you might leave out "Wait for a while" and "Slip downstairs." These are not really images, are they? Slipping downstairs would be an image if she were actually doing it--but she isn't.

If you are writing a paper you would do well to use complete sentences rather than just submitting a list. You could make a good impression by define the word "aubade." It is explained in detail in the Wikipedia article which you can access by the reference link below (I hope!). It is a French word and is pronounced oh-bahd, with the accent on the second syllable.

Richard Wilbur is a prominent modern American poet. You might say a few words about him. See the other reference link below. He calls his poem "A Late Aubade" because an aubade is a traditional morning love song, as you can read in the Wikipedia article, and in his poem it is "almost noon."

They are obviously in an upstairs bedroom. One wonders about their relationship. Whose house is it? Are they married? Is she married to someone else?
