Judges

Claude Opus 5.5 · medium · Pass 1

6.10 Not counted

What the judge sees: Original (Chinese) 这是一幅扁平风格的插画，画着一只白色的鹈鹕形状的鸟骑在一辆深灰色线条画成的自行车上。鸟的翅膀是浅灰色，嘴是橙色的长喙，两条橙色的腿向下伸到车架中间的踏板处，一只浅灰色的翅膀尖伸向车把。背景上方是浅蓝色的天空，右上角有一个黄色的圆形太阳，紧挨着鸟嘴的尖端；画面下方是一条绿色的地面，两个车轮的底部落在这片绿色里。

Original (Chinese) 双脚踩中轴不错，但没有车座，喙和太阳重叠，颈部线条断裂。
