Create an ultra-realistic steampunk portrait of a young black woman with deep, dark skin, focusing on highly photorealistic facial features. Her face should have a smooth texture with sharp, high-contrast lighting that accentuates the depth of her skin tone. She wears a large mechanical gear as an earring, alongside an intricate headpiece made of chains, gears, and small ornaments. The jewelry should be highly detailed, with metallic textures and reflective surfaces. Her outfit features a colorful, vibrant design with rainbow patterns, integrated with small gears and mechanical elements, creating a steampunk-futuristic fusion. The lighting should be focused to bring out the details in both the metallic components and her skin, ensuring the image is rendered in high resolution for a realistic and sharp finish. Avoid an overly illustrated appearance, focusing instead on capturing the realism and contrast between the dark skin and the intricate, brightly lit mechanical details.
