We are looking at his back side. He is arched back and the squash is on his right side. I wasn't thinking of ballet when I did it. I was just thinking of an interesting pose with good gesture.
i know we're looking at his back side, but still his spine is turning into the wrong way... dunno, what i'm speaking of, so i think i'll just be quiet for a while...
I did push it a little but to make good gesture you need to push the pose. It makes it more interesting. Pushing just past reality can be a good thing. Here, he's not bending back that much. He's bending more to our right then anything.
From the pose itself... were you thinking ballette when you drew this? it looks like it... or the matrix-dodging-bullets-style...
