Create a realistic portrait of the writer Gabriela Mistral in an artistic watercolor style , using soft brushstrokes and transparencies typical of the medium. Gabriela is smiling naturally and warmly , with a wide but not forced smile , showing a few teeth. She looks slightly sideways (to the side , out of the frame) , with a playful and authentic expression. Soft , natural lighting , like sunset light , highlights her face with warm nuances of gold and pink. A blurred watercolor background is suggestive but not intrusive. Realistic details in the eyes (natural shine , reflections) , skin texture with subtle imperfections , and expression wrinkles around the eyes from the smile. The style is somewhere between realism and conceptual art , with touches of painterly expressiveness. Balanced colors: browns , ochres , soft blues , and hints of red on the cheeks. A human , emotional , and lively appearance. ,
