example of a description of a poem

Let's say the poem I'm describing is this one by Ezra Pound:

In a Station of the Metro

The apparition of these faces in the crowd;

Petals on a wet, black bough.

notes: this is the whole poem. Also, the Metro refers to the subway system in Paris.

Five-sentence description:

Pound, in just a few words, makes us know that he is recounting a personal experience of an aesthetic kind: the appearance of the people's light-colored faces against the relative darkness of the subway station struck him. He must have thought to himself, "how to describe them?," and come up with his metaphor: the faces were like petals on a wet, black bough. The reader's imagination must zoom away to a place far from a subway station in the middle of a city; it must picture itself near a tree; it's been raining; the petal of a flower that has recently bloomed on that tree has been affixed, by rainwater, to a tree branch. "What were we talking about?" asks the reader. "Oh yes, faces in a subway--yes, they could be like the beautiful flower petal on the branch! How surprising!"
