Portrait photo façon livre d'histoires en style dessin à la main pastel

Transform this photo into a warm, soothing Folk Flat Illustration style. Preserve the original person, pose, clothing, hairstyle, facial expression, and overall composition exactly as they are, while converting the entire image into a clean, hand-drawn flat illustration. The character should have rounded, adorable facial features, soft rosy cheeks, a gentle smile, and natural hand-drawn brush textures. Use a pastel color palette accented with vibrant colors, and incorporate whimsical elements such as flowers, birds, butterflies, hearts, stars, bunting flags, swirls, and handwritten doodles. Keep the original background scene, but simplify it into a charming, storybook-like illustrated landscape. The overall aesthetic should feel warm, dreamy, playful, and artistic—resembling a modern children's picture book or Scandinavian-inspired Folk Art illustration.
