What the judge sees: Original (Chinese) 这是一幅扁平风格的卡通插画:一只白色的鸟骑在一辆深蓝色线条的自行车上。鸟由白色的圆形头部和圆形身体组成,有黑色眼睛、长长的橙色喙,身体中部有一块浅灰蓝色的翅膀,两条橙色细腿向下伸到车架附近,脚是橙色的。背景上部是浅蓝色天空,右上角鸟喙后方有一个淡黄色圆形的太阳,下部是绿色的起伏草地,自行车的两个车轮压在草地上方。

The bird looks like a ball with no pouch, the frame is muddled, and the body floats above the saddle.
