Steps

I have been watching my reference videos very carefully, and I am planning out the steps for the run cycle, I have just drawn these 12 steps from the first reference video.

When the person seems to get up a few steps, he starts to step up, two steps at a time.

Below are some quick drawings of the front of  the body, I drew them again from watching the referencing videos to see how the arms would move and the feet.
