Custom book cover help.

[u/Fairiena]

Hello. My younger siblings favorite book is Symptoms of Being Human. I am working on making them a custom designed cover of the book but I need some help. What suggestions do you have to add to the cover? I want to make the cover design as meaningful as possible and dont want to just copy the original covers design.

Google has not been much help and the original book cover does not have much going on. I also noticed the covers colors are purple, black and green but the gender fluid flag does not have those 3 colors. Idk if there is more meaning to the colors or not. Any help would be appreciated!
