This painting is the one referred to by Nick in the passage. The painting brings out a  dark side about which Nick is referring to by " at once conventional and grotesque, crouching under a sullen, overhanging sky and lustreless moon." Nick is describing the  conformity and underlying darkness that seems to capture the people and West Egg. The painting itself, has wonderful use of color. The dark blues and greens, pop out of the painting. I find it interesting that the little village, is painted in the grays. It's almost as if the town consists of dark forces and nature is a reflection of that. The sky, with it's swirling blues, appears to be thundering, as if maybe troubled by the village.
