How does Raymond Chandler use imagery in The High Window?

Imagery:

"At the end of the corridor, in the angle of the wall, a youngish blond man in a brown suit and a cocoa-colored straw hat with a brown and yellow tropical print band was reading the evening paper with his back to the wall. As I passed him he yawned and tucked the paper under his arm and straightened up"

"He was a big man, rather paunchy, wearing brown and white shoes and sloppy socks and white trousers with thin black stripes, an open neck shirt showing some ginger-colored hair at the top of his chest, and a rough sky-blue sports coat not wider at the shoulders than a two-car garage. He would be about fifty years old and the only thing about him that very much suggested cop was the calm, unwinking unwavering stare of his prominent pale blue eyes, a stare that had no thought of being rude, but that anybody but a cop would feel to be rude. Below his eyes across the top of his cheeks and the bridge of his nose there was a wide path of freckles, like a mine field on a war map."
