Skeletal System Poster

Create a clean educational anatomy poster showing the human skeletal system in anterior and posterior views on a pale cream background. Use a refined academic wall-chart style with precise bone linework, cool gray and ivory bone shading, charcoal labels, and subtle blue accent rules. Include a centered title with crisp in-image text "Human Skeletal System" and subtitle "Anterior and Posterior Views". Label key structures such as "Skull", "Clavicle", "Sternum", "Humerus", "Radius", "Ulna", "Pelvis", "Femur", "Tibia", and "Fibula". Add a compact scale note reading "Adult height reference 175 cm" and a small legend with "Axial" and "Appendicular". Keep the composition symmetrical, scientifically accurate in appearance, suitable for a classroom wall chart, non-gory, clean, precise, and publication-quality.
