I'm thinking of create the illustration by using a text to image model. in this model, we need to prepare what is called "prompt". The prompt needs to be the following:

*sentences or words that describes what the illustration look like 
* objective
* clear
* only includes nouns and adjectives.
* does not include verbs.

And following is the good example of prompt.

" beautiful concept art illustration of a one beautiful kawaii girl in fluttery white dress with wavy hair,symmetrical perfect face fine detail delicate features quiet gaze,a beautiful full body illustration,beautiful europian building background,High-angle shot by void/Re:era and wlop and makotoshinkai and NAME_1 and NAME_2 and KanLiu and rossdraws and  lighting,volumetric lighting,sdorica,reduce saturation,pretty-small-face,fine detailed face,Twice,volumetric top lighting,big kawii eye,bold line painting,soft shadow "

by the way, i'm writing a fiction. in this world, there is a unique sports, "Pee Holding". In the sports, person drinks much water, tries to hold pee as much as possible. a cute girl A loves to do that and is good at doing that because A has trained well.
