Create a black-and-white sketch of a slender, flat-chested girl standing in a detailed steampunk setting. Her long, flowing hair is a unique blend of rich green and copper tones, cascading down her back in soft waves. The hair catches the light in an ethereal way, with strands subtly merging between the two colors. She has striking glowing green eyes that seem to emanate a soft, eerie light, giving her an otherworldly appearance. The girl’s facial features are delicate with a slight, soft smile, and her expression is calm yet mysterious. Her posture is relaxed but confident, with her arms gently at her sides. She is dressed in a steampunk-inspired outfit, with a corset, brass goggles, and leather gloves, all set against a backdrop filled with intricate gears, steam-powered machinery, and Victorian-style architecture. The atmosphere should have a mix of mechanical and fantastical elements, with pipes, cogs, and steam rising in the background, all contributing to the industrial and vintage aesthetic. The scene should have a balanced contrast between the softness of the character and the hard-edged mechanical world around her.
