I chose to do a baseball throw because I thought it could show off anticipation as well as be a good movement to show how the body follows through when you throw something.

Beginning the animation process with stepped keyframes, trying to show the twisting movement of the body and the follow through from the head and torso.

Converting animation to splines to show the movement, various issues showed up.

Further cleaned up the animation, though I think the movements are too robotic and not completely fluid.
