A medium shot from a slightly low angle captures a tall, elegant mature woman standing confidently. She has long, straight rose-gold hair cascading down her back and piercing red eyes with a sharp, intense gaze. As a European royal female warrior, she stands 180cm tall, exuding a cool, refined aura. She wears a pristine white armored dress with intricate detailing and a flowing red cape that billows gently behind her. Her right hand grips the hilt of a long, ornate sword held vertically at her side, while her left hand rests lightly on the pectoral guard, fingers extended with grace. Behind her, floating in the air, is a beautiful koi fish with red-to-white gradient scales and a tail resembling that of a guppy; it is actively blowing small, translucent bubbles. The background features a majestic European castle with high stone walls and pointed towers under a cloudy sky. The art style is clean and hard-edged with firm linework and structured anatomy, typical of modern Korean digital illustration. Colors are controlled and slightly muted, featuring realistic lighting, subtle gradients, and a polished, emotionally restrained atmosphere.
