Kelpie in the Catacombs: A 3D Render

Ultra-detailed photorealistic 3D render of a kelpie inside a damp medieval catacomb. Dim torchlight flickers along moss-covered limestone arches, casting long shadows. The kelpie stands in a shallow pool along a narrow vaulted corridor; its coat is dark, glossy blue-black with iridescent hints, wet strands clinging to its neck and chest, droplets glistening. Its eyes glow amber, reflecting the torchlight. Surroundings include ancient masonry, niches with skulls, creeping mold, and water pooling with ripples. Thick fog and steam drift through the air. Use high dynamic range, global illumination, ray-traced shadows, physically-based rendering, depth of field and subtle motion blur to emphasize reflections on wet surfaces. Style: dark fantasy, cinematic, moody and epic yet intimate. Camera angle is low and close to the water surface, with the kelpie slightly off-center, arches serving as leading lines toward its gaze. Color palette of cool blues and greens with warm torch glow. Mood: eerie, otherworldly, mythic.
