Create a highly realistic portrait of a 40-year-old woman of mixed ethnicity

Create a highly realistic portrait of a 40-year-old woman of mixed ethnicity, weighing 50 kilograms. Her skin tone should reflect a blend of diverse backgrounds, with warm, natural tones. She has expressive eyes that convey wisdom and experience, subtle laugh lines that show a life full of smiles, and her hair is medium length with soft waves. The overall appearance is natural and elegant, with a slight hint of makeup to enhance her features. The lighting should be soft and flattering, capturing the details of her face with precision."
