拙趣涂鸦数字草图

A digital hand-drawn sketch of [subject]. Loose and casual style, presenting a "poorly drawn" doodle aesthetic. Rough, trembling and uneven black outline. Solid color block flat fill, cel-shaded shadows, no gradients, no realistic lighting. Simplified details, minimal facial features (eyes are just simple dots or face without facial features). Background is flat beige or warm off-white. A humorous, low-fi, naive digital illustration style. --ar 3:2
