One more pixel forward, leading leg only! Also, look at the skeletal structure of the spine on google, the body follows that curve pretty closely. Understanding that curve can prevent these kinds of problems in the initial sketch! I'd also add a second arm behind him, since you seem to be drawing the legs and torso in a slightly 3/4ths view! Just a hand will do it!
Also, try to kill the tangent (straight line where you don't want one) along the top of the crotch by deleting the two middle pixels, as it is he looks folded inwards slightly.
