For our most recent Hand Drawn animation project we were given the first and last frame of a character animation and had to fill in the inbetweens, any way that we chose to. It was an exercise in creative motion and sticking to a humanoid character model that was provided for us. The animation had to be a minimum of 12 seconds.

Some things that I'd like to go back and improve:

-His proportions when he's on the ground and his legs are in front of his arms

-Adding more sticky stuff when he lands and generally making it stick around for a few frames longer
