Since last time I have adjusted a lot of the animation. I started by animating the arms so that they move relatively smoothly, and the shoulders now move in the form opposite arm opposite leg. To give the rig shadows I added an area light to the scene, and toned down the intensity so that it didn’t overpower the scene.
I still need to research how to do an endless white background, but in the meantime I am using white planes. Also I need to look at the graph editor to make the transitions between poses more fluid, since the movement still feels a bit clunky.
