Clip 1: The basic forward movement.
Clip 2: The basic forward movement with some ground resistance and head bobbing.
Clip 3: Same as 'Clip 2' but from another angle.
Although I smoothed out the animation in the graph editor, some of the joint movements still seem a little jittery and sudden. I think I'll have to go back and refine the movements a bit more.
