I'm proud of the way I write the narration in my novel. It's almost like poetry, and this is a way of meshing writing styles that I personally love. I'm also proud of the uniqueness of some of the chapter titles, and the fact that the novel managed to make some people cry.
I'm proud of the diversity of the characters and all their hobbies and interests, They truly are a wide range of people, culturally, aesthetically, personality, etc all mixed together. Some of them even have unique ways of speaking based on their country or cultures of origin.
Diva has a lot of urban influence in her speech, while Mad is british, and Jinwoo's speech pattern is unusual for unique reasons.
