How does Anthony Burgess use imagery in The Wanting Seed?

Imagery:

"The young dandy, bright with cyclamen lipstick, twittered at her tears."

"He passed jolly or somnolent dining clubs, corpses, bones, but was not himself molested. The endless city had a smell of roasting flesh and stopped-up drains."

"The War Department is a bit like prostitution: it cleanses the community. If we didn't exist, a great deal of nastiness would bubble up in the State."
