The front and back are working pretty well, especially with the shading on the limbs as they move forward and back. But yeah that East one needs some more attention, at first glance I thought it was supposed to be him walking at a diagonal (down-right).
You're showing a bit too much depth (the front of his body) for it to be a side view. His shoulder should be more or less lined up directly under his head (maybe slightly back if you want a more realistic hunch), and legs should be more or less perfectly lined up as well (the frame when his legs meet straight, you should only see one leg). I'd start there first, hope that helps!
