Gray is depicted with an air of quiet resolve, her silver-gray hair swept back to reveal a determined gaze. She wears a meticulously tailored outfit blending modern academy style with subtle steampunk flourishes: a dark jacket with contrasting piping, a high collar, a layered skirt, and knee-high boots. The figure captures a dynamic stance—one foot planted on a platform that hints at a zeppelin deck—suggesting motion and readiness. Textured fabric textures, sculpted facial expression, and precise accessory details, including a compact satchel and slender weapon-like prop, highlight the craftsmanship and cinematic presence of the character.
