I found this picture on Escher Girls and decided I would try my hand at adjusting the anatomy. The main complaint is that she is merely posing not really fighting this creature. I interpreted it as she finished the battle and is posing with her “trophy”. Anyway, there were quite a few things that were odd with the original. The main issue is that her torso was way too long and her sword arm was not foreshortened correctly.
I ended up making her head larger, fixing her shoulders, giving her a thicker waist, taking the sway out of her back, adjusting her arms, fixing the perspective on her leg, giving her a bikini bottom (cause she was sitting bareback on spines?), I also adjusted her facial features. I decided not to change her costume too much as this character rarely wears more than jewelry.
