Professional executive portrait of a Black South African woman in her mid-40s. Use these exact facial features as reference: round face, dark brown deep-set eyes, broad nose, full lips, dark brown skin tone, short hair pulled back neatly. She is wearing a crisp white executive blazer suit. She stands straight, body angled very slightly to the side, head turned directly forward facing the camera. Arms are crossed confidently across her chest in a strong executive pose. Expression is calm, warm but authoritative. Transparent background (PNG). Full head clearly visible with space above the head. Cropped from mid-thigh up. Studio lighting, photorealistic, high resolution portrait orientation.
