These are some old, 2D animations I did for one of my classes a little over year ago. I did a lot more animations but these are the better of the ones I could find.
This first one is a walk cycle of a kid listening to music.
This one was for an assignment where we had to have a bird dive into water.
I animated this when the assignment was to have someone or something dodge a ball.
This last one was for an assignment where someone had to throw a paper plane.
