Cheerful Black Girl on a Cartoon Train

A cheerful Black girl in cartoon style, sitting by a window inside a bright train carriage. She has natural curly hair, a big smile, wearing a colorful outfit: turquoise top and pink skirt, red sneakers. She is seated on yellow seats with a window to the outside showing a blurred countryside, overhead luggage racks with colorful suitcases, sunlight streaming in. Bold black outlines, flat vibrant colors, soft shading, and a playful, kid-friendly vibe.
