He doesn't have to move around much for it; a knife is wrapped on his ankle if that's hard to see

His pose is seemingly difficult or impossible according to
several positions I have seen of contortionists
but I can say that he just has an abnormally elongated body

This is only one of the few attempts to draw contorted body, so understand my mistakes

I've spend couple of hours looking at contortionist videos and different poses, and google (which didn't help too much) but his anatomy kind of distorted the original pose D:

I left the background smudgy because I felt like it lol

This drawing took me gazillion attempts erasing and redrawing, but it may be feel better about my current art block

hopefully I draw more
