Character Walk- Steps 2

This is a bit more of the steps animation, I am not happy with the way the character moves his head, I aimed to get a sweeping head movement as he moves his head from side to side, I am also unhappy with the way the character moves when he reaches the steps, he stretches his leg and a knee isn't present, this will prove hard when trying to animate him pushing off to walk up the stairs. The arm also shrinks as it moves down to his side, and the head is constantly changing, also the stairs seem to mysteriously grow, I am going to have to re-do all of these mistakes in order for the animation to be at a good standard.
