To get his arm to wave independently, I had to split each section of his body into layers so I could chose which layer I wanted to animate.
In the falling scene, I rotated the subject and placed key frames every 90 degrees. 
The problem I was face with at this point was trying to make him smaller, giving the illusion he was falling down a hole. Making him smaller pulls each of his features down with his feet almost like an anchor, so I had to add more key frames to make him rise in the shot, even though it is not clear when put in front of the chaotic background.
