Judges

Claude Opus 5.5 · medium · Pass 1

6.25 Not counted

What the judge sees: Original (Chinese) 这是一张扁平风格的插画：一只白色的鹈鹕坐在一辆深灰色线条画成的自行车上，背景上方是浅蓝色天空，下方是一条绿色草地。鹈鹕身体是椭圆形，有浅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缕灰色羽毛，橙色的大喙向右伸出，喙下有一个较浅的橙色喉囊。它两条细长的橙色腿向下伸到自行车中间的踏板处，自行车的两个圆形车轮分别在画面的左下方和右下方，压在草地上。

Original (Chinese) 整体合理，但没有踏板，一条腿伸到中轴下方悬空，头顶小钩显得多余。
