What the judge sees: Original (Chinese) 这是一幅扁平风格的插画:一只白色、带灰色翅膀的鸟(有橙色的大喙,形似鹈鹕)骑在一辆红色车架的自行车上。自行车有两个白色车轮,车轮带深蓝色粗轮廓线;鸟的橙色细腿向下伸到脚踏处,自行车后方画有几条短线表示运动。背景是浅蓝色天空,右上角有一个黄色圆形太阳,下方是起伏的绿色草地。

The bird is a bit round and plump, with a short beak, so it doesn't look much like a pelican; the front wheel isn't connected to the frame, and the bike structure is incomplete.

The pelican's beak is passable, but the front wheel is detached from the frame, there's no saddle, and the body hides parts of the bike, making the structure confusing.
