ภาพดูเดิลมินิมอลด้วยปากกาหัวสักหลาด

A [simple hand-drawn doodled style cartoon] sketched with a [black felt-tip pen]. Style: natural marker strokes, slightly wobbly contours, organic imperfections, open line edges, and a warm editorial doodle aesthetic. Composition is flat, minimalist, airy, and understated on a clean paper background. Palette: primarily black ink linework with [sky blue] used strictly as a sparse accent color. Constraints: no vector perfection, no crisp digital gradients, avoid polished shading.
