You have a sense of the poses for running, which is good.

What you have to work on, is to keep the transitions smooth, which mainly include the arm, and leg movements. Don't forget he ain't running straight, you have to make him bounce a bit. (:

Ok thanks alot, should i focus on the torso part of the transitions? The arms i must take care its just that adding the in between frames kinda messes it up at first when i notice a small gap or a too fast transition. But anyway ill keep going.

More CnC if anyone got more advice
