Ultra-detailed 3D portrait of Ludwig van Beethoven, aged around 50, with intense, expressive gaze. Prominent facial wrinkles, furrowed brow, and unkempt gray hair styled in thick, voluminous waves. Classical 18th-century attire: dark coat, high-collared white shirt with a red cravat. Subtle skin imperfections, visible pores, natural lighting with studio cinematic tones. 8K PBR textures for skin, hair, and fabric. Clean UVs, watertight mesh, sculpted for close-up rendering and historical fidelity.
