Seedance 1.5 Pro Prompt: Render a photorealistic 3D underwater scene (4K, 60 fps). A mermaid with detailed scales and flowing hair dives near a sunken ship, carefully picking up pearls from the sandy bottom. Marine life surrounds her: schools of fish, swaying seaweed, rays of sunlight filtering through the water. Suddenly, from the shadow of the wreck, an anglerfish appears — realistic textures, bioluminescence, sharp teeth. The mermaid turns, makes eye contact, and calmly approaches. She kisses the anglerfish gently. A subtle magical effect (soft glow, swirling particles) envelops the creature, and it gradually transforms into a humanoid merman with elegant fins and calm eyes. They exchange a look and swim side by side toward the surface. Cinematic lighting, realistic fluid dynamics, high detail. Music of rachmaninov plays.
