(quick critique - I'm on the road)
Ok, two things stand out, the head has no overlap, it's moving/rotating down as the body moves down. When the body goes down, the head needs to come down a few frames later.
The other thing is your body in the front view, there is still no left to right movement. So when the screen right leg is off the ground, move the body screen left so that the weight is over the screen left leg. Then when the screen left leg is off the ground, you move the body over screen right.
