Underground Ocean in Watercolor Tunnels

A watercolor painting of an underground labyrinth of tunnels flooded with an ocean. Soft washes of blue, teal, and sand drift across mossy stone walls, with stalactites and stalagmites resembling coral and ancient shipwreck debris. Light filters through cracks and skylights, creating gentle beams that scatter on the water’s surface. Schools of luminous fish swim through flooded arches; seaweed sways around stone pillars. The ceiling leaks a dreamy glow, blending the subterranean with the sea, while brushstrokes remain loose and flowing, with grainy paper texture and color bleed characteristic of watercolor. A tranquil, surreal atmosphere that contrasts rigid tunnel geometry with organic, underwater life.
