Judges

Claude Opus 5.5 · medium · Pass 1

6.30 Not counted

What the judge sees: Original (Chinese) 这是一幅扁平风格的插画：一只白色的鹈鹕骑在一辆红色车架的自行车上。鹈鹕有橙黄色的长喙和下方的喉囊、橙色的腿和灰色的翅膀，翅膀向前伸到车把上。自行车有两个黑色车轮，车轮上有细细的灰色辐条，车子停在一条绿色草地上，下面有一道淡淡的阴影。背景是浅蓝色的天空，左上方和上方中间各有一朵白云，右上角有一个黄色的圆形太阳。

Original (Chinese) 喉囊明显，但脖子扭曲、翅膀像管子，只有一只脚踩在踏板上。
