Hand-Drawn Felt-Tip Doodle Style

Draw in a style, as if sketched by a person with a tool. 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 accent_color only as the accent color.
