Just a quick thing I put together. This blew my fucking MIND when my anatomy teacher pointed it out. My drawings instantly got better. You might know it (good for you, I wish I knew it before too T_T) or you might not and it might help you get better.
I did NOT know this! :OOOOO Thank you!
Also note for fic writers: this is why, if two characters of wildly different heights are seated / having sex / otherwise level from the torso up, they’re not going to have a problem mashing their faces together. It’s just their toes that won’t touch.
