How does George R.R. Martin use imagery in A Feast for Crows?

Examples of Imagery:

"Have courage. We came from the sea, and to the sea we must return. Open your mouth and drink deep of god's blessing. Fill your lungs with water, that you may die and be reborn. It does no good to fight."

"We had one king, then five. Now all I see are crows, squabbling over the corpse of Westerose."

"We Dornish are a hot - blooded people, quick to anger and slow to forgive. It would gladden my heart if I could assure you that the Sand Snakes were alone in wanting war, but I will not ell you lies, ser. You have heard my smallfolk in the streets, crying out for me to call my spears. Half my lords agree with them, I fear."
