Siren in the Vampire Castle

Photorealistic render of a siren in a vampire castle. A damp, candlelit Gothic corridor with towering arches, iron chandeliers, and bat silhouettes. Moonlight streams through tall stained glass, reflecting on a wet stone ledge and a shallow pool. The siren stands by the water, her hair dark and slick, pale skin with iridescent blue-green scales along shoulders and arms, and luminous sea-blue eyes. A delicate seashell tiara sits in her hair, dripping with water. She wears a sea-kissed, translucent gown that clings to her form, hinting at shape while remaining tasteful. Surrounding walls feature carved stone, dusty tapestries of sea monsters, and red torchlight. Mist swirls along the floor, and subtle reflections ripple in the water as if her song lures the listener. The scene is rendered in ultra-detailed photorealism with cinematic lighting, depth of field, micro-skin details, water droplets, and moody atmospheric fog.
