Judges

Claude Opus 5.5 · medium · Pass 1

5.45 Not counted

What the judge sees: Original (Chinese) 这是一幅扁平风格的矢量插画：浅蓝色天空下方有一条绿色草地带，草地上方是一辆红色车架、两个黑色圆形车轮的自行车，车头朝右。一只白色的鸟坐在车座上，身体是椭圆形，带灰色翅膀和三角形尾巴，长长的弯脖子顶着圆形的头，头上有一个黑色眼睛和一个大大的橙色喙。鸟的两条橙色细腿往下伸到中间的脚踏处，一根灰色的翅膀尖往前搭在车把上。

Original (Chinese) 造型简洁可辨，但缺少车座和踏板，双脚只汇聚在中轴上。
