Create an ultra-realistic profile portrait of a black woman with deep, dark skin, focusing on photorealistic facial features. Her face should be shown in a side profile with smooth skin, emphasizing her natural beauty and elegance. She wears an intricate steampunk headpiece, filled with large, metallic gears, cogs, and mechanical components, arranged in an ornate, detailed fashion. The lighting should create a sharp contrast, highlighting the delicate balance between her skin and the metallic textures of the headpiece. Her attire is futuristic yet elegant, featuring white fabrics with gold accents and mechanical elements subtly integrated into the design. Her earring should resemble a small, intricate gear, blending into the steampunk theme. Ensure the image has a high resolution and a photorealistic finish, with a clear, high-contrast effect that enhances the depth and details of both the organic and mechanical elements.
