Onion boy walk animation

We need to work on 2 animations for this onion boy model. One is a normal walk and the other is a 180 turn walk. It gave me a big headache for animating this Onion boy because of its big foot. I need to do lots of tweaking in order for its feet not to cut into the ground and I have to avoid knee pops... but i learned a lot from these and it will sure help me in my future animations. Hope that the quality of the clip is good enough for you to see it clearly...
