Help with this scene I want to create

I have a similar scene like this Flowers for Society | the new footwear experience & metaverse and I need help to create it. Please I would really appreciate it.
I have build till now this piece of code three.js dev template - module - JSFiddle - Code Playground.
I am using a model which I cant upload here because is bigger than 8 mb.

Sorry, this is not a workable live example nor does it show a serious attempt of building a scene similar to the showcase you have linked.

Also understand that this type of short, wide-open question do never get proper answers. Related:
