How does Tony Hillerman use imagery in Talking God?

Imagery:

"The body was under the sheltering limbs of a clump of chaimisa, protected from the slanting morning sun by an adjoining bush. From where he stood on the gravel of the railroad embankment, Leaphorn could see the soles of two shoes, their pointed toes aimed upward, two dark gray pant legs, a white shirt, a necktie, a suit coat, still buttoned, and a ground's-eye view of a pale narrow face with oddly pouched cheeks."

"He must look distinctly different: his best felt reservation hat with its silver band, his best leather jacket, his best boots, his rawboned, weather-beaten, homely Navajo face. But the only glances he drew were quick and secretive. He was politely ignored. That seemed odd to Chee."
