How does Ursula K. Le Guin use imagery in Tehanu: The Last Book of Earthsea?

Imagery:

"The child stared at her or at nothing, trying to breathe, and trying again to breathe, and trying again to breathe."

"The dragon turned its immense head and in a completely animal gesture nosed and sniffed at the man's body."

"She did so, and saw the two sides, the two paintings, made one by the light flowing through the silk, so that the clouds and peaks were the towers of the city, and the men and women were winged, and the dragons looked with human eyes."
