From my drawings I converted the poses into frames. These pencil tests are quick animations that demonstrate this. The first video shows an agile person jumping from a high ledge. The next shows 2 children jumping on a soft surface (a bed). It was interesting to learn that when jumping on a soft or springy surface the body moves much differently. For example, the legs stay straight as the force of the surface springing back to position after the downward force of the jump can cause the knees to buckle. The second video demonstrates this!
