What is Nick's impression of gatsby after their meeting at the party?

The first time Nick sees Gatsby he describes him as "standing alone on the marble steps and looking from one group to another with approving eyes. His tanned skin was drawn attractively on his face and his short hair looked as though it was trimmed everyday. I could see nothing sinister about him". After meeting him, Nick sees Gatsby as larger than life. He sees Gatsby as an enigma among the superficial people of East Egg.
