Mermaid Overlooking the Sea Fortress

Ultra-detailed digital painting of a mermaid standing on the mossy battlements of an ancient sea fortress at dusk. Weathered gray stone walls with tall towers, crenellations, sea arches and a broken gate. Crashing waves below and a dramatic sky with purple twilight and a hint of orange on the horizon. The mermaid has an iridescent tail with turquoise and copper scales, flowing hair, and coral jewelry. She holds a softly glowing conch. Bioluminescent algae cling to the walls while sea spray glitters in the air. Warm amber lantern light spills across the stones from a courtyard gate. The scene emphasizes bold digital art style with crisp linework, rich textures of stone and water, dramatic lighting, depth of field, and a cinematic composition.
