How does Robert B. Parker use imagery in Early Autumn: A Spenser Novel?

Imagery:

"I tried to look powerful and rich, but she didn't hurry to catch me."

"I looked at him, white and narrow and cramped, almost birdlike, with his shoulders hunched and his head down. He needed a haircut. He had hangnails. What an unlovely little bastard."

"The urban renewers had struck again. They'd evicted me, a fortune-teller, and a bookie from the corner of Mass. Ave. and Boylston, moved in with sandblasters and bleached oak and plant hangers, and last I looked appeared to be turning the place into a Marin County whorehouse."
