Create a hyper-realistic 3D model of Lord Yamaraj, the Hindu God of Death, with dark blue skin, a muscular build, a stern expression, a thick mustache, and hair tied in a topknot. He wears a golden crown and a traditional dhoti with intricate patterns. He holds the Yama Danda (staff) in one hand and the Pasha (noose) in the other. His eyes glow with a divine light, and he is surrounded by a subtle aura. He is seated on a majestic black buffalo, his divine mount, which has detailed fur and an ornate saddle with golden trims and gemstones. The model should feature ultra-detailed PBR textures, a high-poly mesh, and dramatic lighting with a strong key light from the side to enhance realism.
