A cinematic ultra-realistic scene of a young woman with LONG DARK-BROWN hair, wearing a flowing white dress and high heels, walking away from the camera through a vast underwater coral corridor, seen from behind, inside a crystal-clear glass oceanarium tunnel with transparent walls and ceiling, towering walls of vivid coral reefs in shades of red, pink, peach, and crimson stretching on both sides, colorful tropical fish drifting slowly around the corridor, soft rays of sunlight filtering down from far above like in deep water, subtle reflections rippling across the glass surfaces, serene and immersive atmosphere filled with wonder and quiet awe, natural underwater light diffusion, realistic skin and hair texture, photorealistic depth and scale, shot on GoPro Hero 11, ultra-wide lens perspective, rich coral reds contrasted with soft teal and blue tones
