Here I tried to demonstrate someone sneaking, as if they were trying to avoid being seen and doing something mischievious. I used the basic puppet and After Effects to create an initial cycle and then when I was happy I did a character overlay on top using Photoshop. I then imported the .jpeg sequence back into After Effects and rendered it out with a table. I used videos from youtube for inspiration.
I included pauses in the cycle to slow down the movement and stretched one cycle to just over 2 seconds rather than the 1 second in the other cycles. This was to make the movement seem more calculated and careful.
