A young 22 years old woman lies on a floating air mattress on a calm, crystal-clear, turquoise sea, her body perfectly tanned, her long blonde hair spread softly around her shoulders. She wears a simple, stylish bikini, her skin glowing in the warm sunlight, and her facial features are highly detailed, smooth, and naturally beautiful. She has a relaxed, silent smile, expressing peace, confidence, and effortless charm. The scene is viewed from directly above, giving a clear, top-down perspective of the floating air mattress, the woman, and the shimmering water around her. Sun rays pierce the surface of the sea, creating bright reflections and soft patterns on the water below. Beneath the woman, deep in the transparent water, a massive shark swims slowly and silently, its dark, powerful shape contrasting strongly with the bright of the tropical colors of the scene. The shark is enormous, majestic, and clearly visible, creating a sense of tension and fascination while maintaining a beautifully composed, cinematic atmosphere. The overall scene feels warm, summery, peaceful, and dramatic at the same time, with high detail, photorealistic textures, soft shadows, bright highlights, and maximum clarity in both the woman and the underwater environment
