**“A bright, ultra-clean, hyper-realistic underwater construction scene set inside a massive transparent dome located on the ocean floor. Three professional construction workers wearing advanced light-colored deep-sea diving suits with high-visibility face shields, polished metal oxygen tanks, reinforced gloves, and utility belts are working meticulously. The water around them is crystal-clear, with extremely high visibility—soft golden sunlight filters down from the surface, creating gentle, diffused beams that illuminate every detail with stunning clarity.** **The seafloor is smooth and organized, covered with pale sand, carefully arranged coral formations, and clusters of colorful fish swimming peacefully nearby. No murkiness—everything looks freshly washed, clean, and vibrant. Floating micro-particles shimmer in the water, adding depth without reducing clarity.** **One worker is carrying smooth, perfectly shaped concrete blocks toward the foundation area. Another worker guides a large transparent architectural panel into place while a robotic underwater arm assists, its mechanical joints gleaming under the sunlight. The third worker is kneeling near the base structure, inspecting alignment using a bright white industrial underwater flashlight that casts sharp, realistic shadows.** **In the background, parts of the futuristic underwater city are visible—sleek, polished metal frameworks, glass corridors, soft glowing lights embedded into the dome walls, and clean architectural curves inspired by modern eco-friendly design. The dome overhead catches sunlight in a beautiful way, creating natural reflections that dance across the sand.** **The entire scene is filmed in premium cinematic quality, with ultra-sharp textures, perfectly balanced natural colors, clean white highlights, smooth gradients, and no visual noise. Shot with a wide-angle cinema lens (28mm), deep depth of field, 8K HDR resolution, crisp contrast, and precise lighting that enhances the bright, fresh, realistic atmosphere. A calm, optimistic, futuristic mood fills the entire environment.”**
