Confident Engineer: Portrait of Strength

Create a portrait of a confident African female engineer in a modern office setting. Her oval face features high cheekbones, warm brown skin, and expressive almond-shaped eyes that reflect determination. She has tightly coiled hair styled into a professional updo, adorned with subtle gold hairpins. Capture her wearing a tailored navy blue blazer over a crisp white blouse, with a hint of a silver necklace peeking through. The lighting is soft yet focused, casting gentle shadows that highlight her strong jawline and the contours of her face. She is smiling slightly, exuding warmth and intelligence. The background includes blueprints and engineering tools, subtly blurred to maintain focus on her. Use a 50mm lens for a shallow depth of field, ensuring her face is sharp while the background remains soft. Render in a realistic style, reminiscent of contemporary portrait photography, to convey professionalism and approachability.
