Maya Class - Walk Cycle Key Pose Breakdown

This is the complete set of key poses for this particular walk cycle. I started them in last Thursdays Maya class, and finished them off today, moving on to the inbetweens. I'm finding it a tad difficult in visualising the movement but I'm hoping that will become easier when the in between motions are in there. I also need to work on the curvature of the spine, positioning of the head and so on.
