1girl, a young woman as a lifeguard perched on a sunlit white lifeguard tower, wearing a simple white T-shirt and vibrant red shorts, curly brown hair cascading around her shoulders, blowing a whistle with focus, the sunny beach stretching out before her, eyes the color of hazel, the scene is captured in 8k resolution with professional color grading, the depth of field brings her into sharp focus against the blurred sea background, creating a vivid summer atmosphere.
