What the judge sees: Original (Chinese) 这是一幅扁平风格的卡通插画:画面中央,一只白色的鹈鹕骑在一辆红色车架的自行车上。鹈鹕有圆形的头、黑色的眼睛、橙黄色的大喙,灰色描边的翅膀向前伸出握住黑色车把,两条橙色的腿向下踩在踏板上。自行车有两个黑色轮胎、灰色辐条,中间是链盘;背景上方是浅蓝色天空,右上角有一个淡黄色的圆形太阳,下方是一条绿色的地面,车轮下有灰色阴影。

Complete build and a reasonable pose, but the beak is a bit short, making it look more like a duck than a pelican.
