Anatomy Poster

Create a clean educational anatomy poster showing the human muscular system in anterior and posterior views on a pale cream background. Use an academic but visually refined style with precise linework, muted reds and umbers for muscle groups, cool gray bones, and thin charcoal labels. Include a centered title with crisp in-image text "Human Muscular System" and a subtitle "Anterior and Posterior Views". Label key structures such as "Deltoid", "Pectoralis Major", "Rectus Abdominis", "Biceps Femoris", "Gastrocnemius", and "Trapezius". Add a compact scale note reading "Adult height reference 175 cm" and a small legend with "Superficial" and "Deep". Keep the composition symmetrical, scientifically accurate in appearance, and suitable for a classroom wall chart. Prioritize correct labels, crisp typography, clean hierarchy, subtle shading, and publication-quality educational clarity without gore or excessive realism.
