Photoreal Reaper in a Crystal Cave

Photorealistic depiction of a tall Grim Reaper standing in a vast crystal cave. The figure wears a tattered midnight black hooded cloak that drapes over skeletal shoulders; the hood shadows a pale skull like face. In one skeletal hand he carries a long ancient scythe with a dark slightly rusted blade and runic etchings along the blade and haft. The cave walls are made of massive quartz and amethyst crystals with facets that catch and refract light into a spectrum of blues purples and pinks. Crystalline pillars rise from the floor and stalactites hang from the ceiling. The ground is slick with a thin reflective pool and scattered shards. A soft bioluminescent glow from embedded minerals illuminates the scene, casting ethereal rays and prism reflections across the reaper and crystals. Mist swirls in the air, giving a sense of depth and scale. The camera angle is slightly low looking up toward the imposing figure, with a shallow depth of field that keeps the reaper sharp while the cavern dissolves into a glowing bokeh of crystal forms in the background. Ultra detailed textures include wet cloak fabric, frost like crystal facets, metallic scythe, damp cave floor, light scattering through prisms. The mood is somber, awe inspiring with a hint of menace and power.
