Pareja flotando en jardín submarino

Cinematic underwater romantic portrait, vertical 9:16 framing. A happy young couple floats gently hand-in-hand above a breathtaking [underwater flower garden] filled with colorful coral blossoms, swaying sea grass, and glowing aquatic plants. Crystal-clear sapphire-blue water surrounds them as golden sunlight streams down from the surface, casting volumetric light rays and intricate caustic patterns across their faces and the sea floor. Tiny tropical fish and delicate oxygen bubbles drift gracefully through the scene. The young man wears a [fitted black t-shirt], his curly dark hair drifting naturally in the water currents, with thin round glasses catching subtle sun reflections, wearing a warm, joyful smile as he looks at his partner. The young woman wears an [elegant white sleeveless top] with flowing black high-waisted bottoms, her long dark-brown wavy hair billowing like silk ribbons, gazing back with radiant laughter and deep affection. Soft glowing jellyfish and distant schools of exotic fish add depth to the background. 35mm cinematic lens, f/1.8 aperture, shallow depth of field, realistic water dynamics, deep ocean blues, emerald greens, and turquoise highlights.
