Generate an ultra-realistic steampunk portrait of a black woman with deep, dark skin. Her face should be highly detailed and photorealistic, with a smooth, shiny texture that highlights her natural features. Her headpiece is intricately adorned with numerous metallic gears, cogs, and clock elements, all meticulously layered to create a visually complex and dynamic design. The mechanical components should be highly detailed, with a focus on metallic textures and rusted edges for realism. Her face has colorful textured designs that blend organic and mechanical elements, with intricate patterns across her cheek. Her attire features mechanical elements, with gears and industrial motifs, combined with fine details such as stitching and lacework on her collar. The lighting should create a sharp contrast, highlighting the details of both her skin and the metallic components. Ensure that the image is rendered in high resolution, with a focus on photorealism, especially in the facial details, while maintaining a clear and vivid contrast between the organic and mechanical aspects of the design.
