Black Felt-Tip Daydream

Draw a simple hand-drawn doodle-style cartoon, as if sketched by a person using a black felt-tip pen. Use natural marker strokes, slightly wobbly contours, subtle handmade imperfections, occasional open line ends, and a warm editorial sketchbook feel. Keep the composition airy, flat, minimal, and understated, avoiding polished vector smoothness or overly crisp digital precision. Use only black for the drawing with sky blue as the sole accent color.
