How he writes faces

She was arrestingly beautiful. The color in her cheeks was centered like the color in a picture -- it was not a 'high' color, but a sort of fluctuating and feverish warmth, so shaded that it seemed at any moment it would recede and disappear. This color and the mobility of her mouth gave a continual impression of flux, of intense life, of passionate vitality -- balanced only partially by the sad luxury of her eyes." 

-F. Scott Fitzgerald, "Winter Dreams"
