Walk cycle

My first walk cycle.This is a basis side walk,just movement of legs,hands and hair.

The second one.Animals with 4 legs are similar to human being,in order to keep their balance their forelegs in left and the rear legs in right must touch the floor at the same time.In addition,the lines of legs in left and in right are not parallel lines.

The third one.There is a bear walks up close.I used simple lines to draw this one,because I thinks simple motions are more helpful for me to learn how to draw walk cycles in different distance.First of all,I draw a few lines to confirm perspective relation,and then I draw general walk steps in different sizes on basis of those lines,like this:
