Claude Opus 5.5 · medium · Pass 1

4.90 Not counted

What the judge sees: Original (Chinese) 这是一幅扁平风格的插画：浅蓝色背景，底部有一条绿色地面带。画面中央是一辆用深灰色线条画的自行车，有两个圆形车轮和一个三角形车架，车把在右侧。车上骑着一只白色的鸟，身体是椭圆形，脖子细长弯曲，右上方是圆头和黑色眼睛，有一个很大的橙色喙；它的灰色翅膀向前伸到车把上，两条细长的橙色腿向下伸向脚踏处，身体左侧还有一个灰色的尖尾巴。

Original (Chinese) 鹈鹕辨识度尚可，但车架结构不合理，缺少踏板和车座，腿悬空。
