I was on DeviantArt one day and I saw a submission by a comic artist that made the front page.
The left image is a cover for Grimm Fairy Tales - the right side is my own lines trying to give more of a structure to it.
The original image has little to no ribs because the artist was trying to show the breasts from behind her arms- ironically it made her breasts sag really low. And she seems to be lacking organs in her torso.
I know I’m not a professional but I hope the version I did is a little more palatable.
Very good breakdown. :) She looks less like an angular Tetris block. A lot of artists seem to really like centaur women.
