How does Fitzgerald use details of setting and imagery to establish a mood in another chapter?

In chapter 5 of the Great Gatsby, when Daisy and Nick take a tour of Gatsby's house, there is a contrasts in mood from chapter 2 since the condition of Gatsby's house seems flawless creating the atmosphere to be calm and relaxed. The perfect conditioned property is first described as "the sparkling odour of jonquils and the frothy odour of hawthorn and plum blossoms". The diction used in this quotation "sparkling, plum and frothy" express the perfection Gatsby's garden is in creating a comforting mood. The quotation also uses the repetition of and which emphasises the pristine condition of the garden. The relaxed and calm environment is also described when Fitzgerald describes the noise as "no sound but bird voices in the trees" which tells the reader that no flaws are seen using all types of senses. This relaxed tempo continuous throughout this scene, for example when Gatsby says “I’ve got a man in England who buys me clothes. He sends over a selection of things at the beginning of each season, spring and fall.” This shows how Gatsby truly cares about the way he displays himself and what he owns like his house and cars to others and especially Daisy. Again how Gatsby states “I’ve got a man in England" in such a calm manner shows another flawless side of himself. Finally throughout this scene, Fitzgerald uses the 5 senses using diction such as "odour, sound, seen, felt, etc" to describe perfect state of Gatsby's house and garden.
