Create an image of a female character inspired by Marvel's Black Cat, in a realistic art style. ((She has an extremely large chest)) and wears a tight black catsuit with a full-covering design that emphasizes her body shape and contours, with no cutouts. She wears Black Cat's classic black mask, leaving only her eyes exposed, adding to her mysterious allure. She has long brown hair, and her expression is confident and seductive. Her body is full-figured, with slightly soft, curvy, and proportional lines. Her posture is graceful yet powerful, as if she's ready to pounce or leap at any moment. The background is a realistic cityscape at night, with moonlight casting deep shadows, enhancing the mysterious and intense atmosphere. The entire scene should be dynamic, highlighting her agility and expertise as a thief.
