Ahh, this is one of my favorites! This is called “Taken” – it’s meant to give the impression of a soul being taken from the mortal cage of a body. Hence the drastic pose of the skeleton. I’m aware there are no legs or hands but the idea is there and I think the abstract-ness of the missing limbs helps with the illusion of a quick release.
I do believe I am very, very happy with this sketch. 🙂
