Photoreal Mermaid on a University Campus

Photorealistic mermaid perched on the edge of a weathered stone university courtyard fountain, with water ripples and droplets. She has a long, flowing sea-blue and emerald tail with iridescent scales, and dark teal hair catching the light. The upper body is modestly covered by a translucent seashell-pattern shawl. Around her, students in casual autumn clothing walk by, marble statues dot the square, ivy-covered brick buildings and a glass atrium rise in the background. Warm golden-hour sunlight bathes the scene; reflections shimmer on the wet stone, and gentle spray adds life to the shot. The image should be high-resolution, cinematic, photorealistic, with shallow depth of field, crisp details on scales, hair, and water droplets, 8k realism.
