The walking cycle loop is not as easy as I thought because we see people walking everyday so if something goes wrong, it will be extremely obvious.

Walking cycle is about up and down, and the frames between them. When one foot is about to goes down but not yet, the body and head is right the top position because another leg is straight and tiptone. After that, when two legs finished into a shape of a triangle and front foot touch the ground with barycenter moves on it, head and body are at the low bottom position.

Mood change is very good for us to figure out how different walks work.

Distance of each steps, timing, speed, X and Y direction move, location of barycenter, and movements of body, arms and head.

But the most important thing is, references! Take videos and features will be much clear.
