Torso and Neck Deformations during Walk Cycle

Hi All,

     I have a Puppet that shows a Slight deformation to the Stomach/ Torso and Neck during a Walk Cycle.

     Both seem to get elongated vertically. The Stomach shows a point along its lower edge. The neck appears to elongate and bounce, leaving the Head steady.

      I've included a Reference Image of the Scene below, followed by several Screengrabs of different layers in the Puppet. Finally, I've attached a video of the Puppet Walking.

     Thanks in advance for your suggestions.

Regards,

Rajnesh
