What the judge sees: Original (Chinese) 这是一幅扁平风格的插画,画面中央是一只白色的卡通鹈鹕,它有灰蓝色的翅膀、黑色圆眼睛和一个很大的橙色喙,正骑在一辆深蓝色线条勾勒的自行车上,两条橙色细腿往下伸向脚踏。自行车有两个浅蓝色填充的圆形车轮,停在一片绿色的缓坡草地上,车下有一道深绿色的椭圆形阴影。背景是浅蓝色的天空,右上角有一个淡黄色的圆形太阳,鹈鹕的左侧和右侧各有几条蓝色的短横线。

Frame is jumbled, there are no pedals, and the bird floats above the bike, so the pose doesn't work.
