Kelpie Concept Art in an Underground City

Ultra-detailed concept art of a kelpie in an underground city. A sleek, water-slicked kelpie stands at the edge of a dim subterranean canal, its dark coat glossy as wet stone, mane and tail flowing like liquid, and eyes glowing turquoise. Basalt arches and carved stone walls frame the scene, with brass steam pipes, iron railings, and hanging lanterns that cast cold blue-green bioluminescent light. The canal surface ripples with reflected glow; damp moss and lichens cling to bricks, mineral veins shimmer in the walls. In the background, an expansive cavern reveals more canals, stone bridges, and distant waterfalls carving through rock. The aesthetic blends dark fantasy and steampunk: ornate gears, glass conduits, weathered brass accents. Cinematic lighting, wide-angle composition with the kelpie as the focal point, dynamic perspective from slightly below, painterly textures or photoreal detail. Palette: deep blues, teals, emerald greens, copper, with misty white steam. Style: concept art, dark fantasy creature design, epic underground cityscape.
