I told myself that I would revisit this drawing specifically because Sukuna's so difficult to draw. He has two eye balls, marks on his face, and a strange ear shape. His face needs to leave space for all of that while still looking normal enough. Then his bodily proportions are just big as hell. So I wanted to challenge myself with getting his proportions to be believable while staying true to his canon design, not just forcing him to look more human/normal. The most liberty I took was probably the L shaped tattoo, since I always wanted to try drawing it imitating a strong jawline.
I've spent a lot of time practicing anatomy, understanding proportions, and challenging my own tastes for design choices. If I had to describe my "style," I'd just say I want to draw with dimension, not any specific style.
