What the judge sees: Original (Chinese) 这是一幅扁平风格插画,画面中央是一只白色的鸟,它有一个黑色圆眼、一个向右伸出的长长的橙色喙,胸前有一块灰色的翅膀形状,坐在一辆深蓝色线条的自行车上。鸟的两条细细的橙色腿向下伸,橙色的脚踩在自行车车架附近的踏板位置;自行车的两个圆形车轮里面填着浅蓝色,右边是车把。背景上半部分是浅蓝色的天空,右上角有一个淡黄色的圆形太阳,下方是一片弧形的绿色草地。

The bird looks more like a duck or seagull, has no pouch, the frame is crude, and the feet and pedals are in the wrong places too.
