What does the narrator admire about gatsby in chapter one?

One main feature that Nick admires about Gatsby is his mysterious character. This is clear as Fitzgerald uses a semantic field of mystery when describing him; 'moonlight' 'shadow' 'silhouette'. Nick romanticises this first sighting of Gatsby using extravagant setting detail 'silver pepper of the stars', 'wings beating in the trees'. This shows Nick's blatant fascination with the eponymous character.
