Joyful Moment by an Icelandic Lush Waterfall

A photorealistic 8k image of a person standing on a moss-covered rock beside a powerful Icelandic waterfall. Lush green cliffs, thick moss, and black basalt textures frame turquoise water cascading into crystal spray. Mist lifts into a faint rainbow as sunlight breaks through a soft sky. The subject wears a bright red waterproof jacket, hiking pants, and sturdy boots, arms raised in joy, wind tousling hair, droplets glistening on skin. Cinematic lighting, shallow depth of field that keeps the person sharp while slightly blurring the background, hyper-detailed textures of damp rocks, glistening water spray, and vibrant greenery. Mood: exhilaration and serene natural beauty, wide-angle composition with expansive landscape cues.
