An underwater low-angle shot looking straight up at a small wooden rowboat floating on the sunny sea surface. In the mid-ground, a beautiful mermaid with a completely human female upper body and a gorgeous black-skinned woman's face is swimming. She has a voluptuous figure with natural dark skin texturing. Her hair is made of flowing green seaweed and kelp floating gracefully in the water. She has striking biofluorescent blue eyes with black irises and gold pupils. From the waist down, she has a stunning mermaid tail with shimmering black and blue scales. The camera is positioned deep below, capturing the boat silhouetted against the bright surface light. Sunlight filters down, casting beautiful light rays, (caustics), across her skin and scales. Cinematic lighting, highly detailed, photorealistic, 8k resolution.
