4.70

What the judge sees: Original (Chinese) 这是一幅扁平风格的插画,画面中央有一只白色的圆胖鸟,长着橙色的大喙,翅膀是浅灰蓝色,它用橙色的细腿踩着一辆红色车架的自行车。自行车有两个深色轮子,中间有灰色辐条,停在画面下方的绿色草地上,草地上有一条深绿色的横线。背景是浅蓝色的天空,右上角有一个淡黄色的圆形太阳,自行车左右两侧各有几条白色横线。

The bird is too round with too short a beak to look like a pelican; its body blocks the frame and its feet are in the wrong place too.
