You really need to learn anatomy. The shoulders, body, arms and legs are all pointed straight at the screen, even though they're intended to be at angle. There's no neck, his head's an awkward circle, and the proportions are all wrong. I really suggest that you study up. Like, find tutorials on the human body and read them.

But well, I think a good place to start with is just to focus on the first idle pose for now. Try shifting the angle of the body over to match the way the head and feet are angled a little better. See if you can add a neck in while you're at it. If it's not coming out right, check out some reference pictures.
