A simple hand-drawn doodle illustration of the reference photo, sketched as if using a [black marker]. Features natural marker strokes with slightly [wobbly lines], subtle hand-drawn imperfections, slightly open contours, and a warm editorial aesthetic. Flat, airy, and understated, avoiding clean vector linework and overly polished digital perfection. Uses [sky blue] sparingly only as an accent color against a plain white background.
