Photo to Folk Flat Illustration

Transform this photo into a warm and gentle folk-style flat illustration. Completely preserving the original characters, poses, clothing, hairstyles, facial expressions, and overall composition, while transforming the entire image into a clean, hand-drawn flat illustration. The character should have rounded, cute facial features, soft pink cheeks, a gentle smile, and natural hand-drawn brushstroke textures. Soft tones accented with vibrant colors are used, incorporating whimsical elements such as flowers, birds, butterflies, hearts, stars, flags, swirls, and handwritten graffiti. The original background scene is preserved, but simplified into a charming, fairy-tale-like illustrated landscape. The overall aesthetic should feel warm, dreamy, playful, and artistic—similar to modern children's picture books or Nordic-inspired folk art illustrations.
