I think it reasonable why the artist didn't draw edith extremely battered like how the novel described, It can caused the reader to feels unease to see our edith like that. Imagined edith face like also make me uncunny, i love edith design.
I make a webtoon too, but i'm not popular, so i know how it feels when i have to draw a character like in edith's position (sorry for my bad English, not my main language)
