I saw a meme about how if you want to draw moe anime girls first you must learn to draw the entire detailed muscular and skeletal system of middle-aged men. Years ago I tried to learn anatomy from Wikipedia for this purpose, so I have an idea of what goes wear. I started to draw Sakuya starting at the bones as a way to kinda play with that idea, though since I’ve only drawn her bones and muscles so far it isn’t identifiable as her.
