Place the skeleton character in a transparent lower-body skeletal view demonstrating biomechanical stress traveling upward from the foot. Show the ankle pronating inward, the knee rotating under pressure, calf muscles tightening, and the lumbar spine compensating with glowing stress lines climbing from heel to back. Keep the same detailed 3D anatomy style. Use dark cinematic industrial lighting with red neural stress effects and x-ray skeletal overlays. Shoot from a rotating side-profile dolly camera with smooth motion through joints and muscles. Rendered in clean cinematic 3D, highly detailed.
