Create an ultra-realistic steampunk portrait of a young black woman with dark, smooth skin, focusing on highly detailed, photorealistic facial features. Her face should have a deep tone with sharp contrast, highlighting her natural beauty and the intricate mechanical elements integrated into her headpiece and attire. The headpiece should feature a large metallic clock mechanism, with gears and cogs prominently placed over her braided hair. Her attire should be composed of a combination of leather and metallic elements, featuring mechanical components, chains, and a small pocket watch hanging by her neck. The lighting should create a striking contrast between her dark skin, the metallic elements, and the soft pink accents in her outfit. Ensure the image is rendered in high resolution, emphasizing photorealism in the face and sharp, detailed mechanical parts, avoiding an overly illustrated or stylized look. Focus on making the lighting and overall contrast vivid and clear.
