一张[主题]的数字手绘草图。风格松散、随意，呈现出一种“画工拙劣”的涂鸦美学。黑色轮廓线粗糙、颤抖且不均匀。采用实色色块平涂，赛璐珞风格阴影（cel-shaded），无渐变，无写实光影。细节简化，极简的面部特征（眼睛仅为简单的圆点，或者是无五官的面孔）。背景为平涂的米色或暖米白色。一种幽默、低保真、稚拙的数字插画风格。 --ar 3:2
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
