Ligne lâche avec style de couleur d'accent

Transform this image into a minimalist line drawing with a loose, sketchbook-style look. Use expressive black ink lines with irregular, hand-drawn contours. The background should remain white and clean, with no shading or textures. Highlight only one or two elements in solid color - such as a red scarf, blue umbrella, or yellow boots - to create visual focus. The overall style should feel light, spontaneous, and emotionally charming, like a page from a children’s illustration sketchbook. The final result should be simple yet evocative, capturing the subject with minimal strokes and one pop of color.
