A minimal, surreal, high-saturation illustrative painting with a deeply poetic and evocative (有意境) quality. Top-down perspective looking into a vast, deep, immersive ocean expanse of saturated cyan, teal, and cerulean blue. Near the bottom center, a single, minuscule figure, wearing a traditional Asian douli conical hat and an orange robe, stands alone on a tiny, submerged dark rock ledge, holding a long, thin fishing rod. Swirling above and around the figure are three colossal, ancient, luminous blue koi-like fish-sharks. Their skin is luminous and textured with intricate, metallic gold and copper patina marks. They emit a soft, diffused bioluminescent glow. The scale difference is extreme, making the fish feel ancient and massive, and the world endless. Clean illustrative rendering with rich jewel tones, magical realism
