How does Amy Tan use imagery in Two Kinds?

Imagery:

“In all of my imaginings, I was filled with a sense that I would soon become perfect.”

“Before going to bed that night, I looked in the mirror above the bathroom sink and when I saw only my face staring back—and that it would always be this ordinary face—I began to cry.”

“The part I liked to practice best was the fancy curtsy: right foot out, touch the rose on the carpet with a pointed foot, sweep to the side, left leg bends, look up and smile.”
