Can someone elaborate on the following themes for the great gatsby?

The green light is a symbol of transcendence, enlightenment, and virtue. This is the point of the novel but the characters become too distracted by "worldly" things like greed, lust, sin, and murder. The valley of ashes represents hell, and the billboard with the gles represents judgment. God is the eternal judge and so the billboard is also a reminder that "God is always watching". The novel was written in the "Jazz Age". This was a time of artistic creation and many would even say a new American renaissance. F. Scott Fitzgerald is recognized as a brilliant writer because of his many contributions. He and Ernest Hemingway were contemporaries but did not always agree about politics. Hemingway moved to Cuba.
