I don't know what my options are but he has a very positive look when it comes to gatsby. He looks up to gatsby but nick is also very judgemental so toward the end of the book his view towards gatsby isn't the best. Nick wanted daisy so I think he was slightly jealous but overall they like you to write that nick used a lot of amplification, analogy could work, many metaphors, or maybe even similes. I hope I helped.
