Create an image of a child standing on a city sidewalk during twilight. The child is wearing a bright orange safety vest with reflective stripes, paired with a dark hoodie underneath. Instead of a backpack, they're carrying a messenger bag in a contrasting blue color. The background features a modern urban setting with blurred lights from shops and surrounding buildings, and a row of bicycles parked nearby. The overall atmosphere conveys a sense of awareness and safety in an urban environment.
