Sky Blue Felt-Tip Doodle

Draw in a simple hand-drawn doodled style cartoon, as if sketched by a person with a black felt-tip pen. Use natural marker lines, slightly wobbly contours, subtle hand-drawn imperfections, slightly open edges, and a warm editorial doodle feeling. Avoid polished vector-clean results, avoid overly crisp digital perfection, and keep the image simple, airy, flat, and understated. Use sky blue only as the accent color.
