very tall, slim, and athletic goth girl sitting in a relaxed pose in a modern gym. Her legs are casually spread or slightly bent, arms resting loosely, exuding confidence and calm. She has pale porcelain skin, long straight jet-black hair, (no bangs), and strikingly beautiful facial features. Her piercing ice-blue eyes are enhanced with heavy black eyeliner and smoky eyeshadow. She wears matte black lipstick, has subtle piercings, (nose ring, eyebrow stud), and black nail polish. A small, detailed tattoo is visible on her upper arm. Her outfit includes tight black high-waisted leggings, a cropped black sports top with gothic elements like straps or lace, fingerless gloves, a black choker, and black sneakers. She is surrounded by modern gym equipment in a dimly lit, moody environment with cinematic lighting and soft shadows. Realistic style, ultra-detailed, full body, high resolution, sharp focus.
