Minh họa phong cách phim hoạt hình Stop Motion của Mỹ thập niên 90

Transform this image into a 90s American cartoon cel-style illustration. Use thick black outlines, flat bold colors, and sharp cel shading with hard shadows. Emphasize exaggerated facial expressions and stylized, geometric character shapes. The background should be flat or minimal to keep the focus on the character. The whole image should feel like a frame from a Saturday morning cartoon. 将这张图片转化为 90 年代美国卡通片定格动画风格插画。使用粗黑轮廓线、平面化鲜明的颜色，以及锐利的定格动画阴影效果和硬阴影。强调夸张的面部表情和风格化的几何角色形状。背景应为平面或极简，以突出角色。整张图片应感觉像是从周六早间卡通片中截取的一帧。
