Judges

Claude Opus 5.5 · medium · Pass 1

6.60 Not counted

What the judge sees: Original (Chinese) 这是一幅扁平风格的插画：一只白色的鸟骑在一辆红色车架的自行车上。鸟的脖子又长又弯，喙是橙黄色的、下方有喉囊，两条细长的橙色腿伸向脚踏，一只灰白色的翅膀向前伸到车把上。自行车有两个黑色轮廓的圆形车轮，下方是绿色草地，背景是浅蓝色天空，右上角有一个淡黄色的圆形太阳。

Original (Chinese) 整体可辨且姿态到位，但车架红黑线条杂乱，双腿交叉显得别扭。

  • Two wheels: Yes
