How does Bret Easton Ellis use imagery in Glamorama: A Novel?

Imagery:

"I'm a knockout, Dad. A total knockout. I'm rippin'. Things are happening. I'm in control of all the elements. You are laughing somewhat jaggedly, Dad, but I am in continuous flux."

I'm a bad boy. I'm a legend. But on reality everything's a big world party and there are no VIP rooms."
