An 11-frame walk cycle with a stickman as my test subject. Did better than I thought!
For the legs I animated them one leg at a time, and used inbetween frames to make sure the movements properly connected. I also added the floor to make sure at least one foot was on a certain level at all times. When I was done with the legs, I decided to add a top half to the body, just for show. I used the human body as a reference. It was hard to track the hand movements like a human, so the final result may look janky.
