Blue Doodle on White

Draw in a simple hand-drawn doodled cartoon style, as if sketched by hand with a black felt-tip pen. Use organic marker strokes, gently shaky outlines, tiny imperfections, occasional open contours, and a warm editorial sketchbook charm. Keep the composition airy, minimal, flat, and quietly playful, avoiding polished vector smoothness or overly precise digital rendering. Limit the palette to black and white with sky blue as the only accent color, letting that blue appear sparingly for a soft, fresh visual pop.
