How does Mark Winegardner use imagery in The Godfather Returns?

Imagery:

"He watched her size him up. He watched her face go slowly slack, watched her make herself not say she wasn't going anywhere, watched her swallow her desire to ask to hear the story. She didn't say a word."

"Hagen had no idea how long he'd been beating the steering wheel when he caught sight of himself, red-faced and sweating, a heart attack waiting to happen. He took a deep breath. He pulled out a comb and put himself together."
