What the judge sees: Original (Chinese) 这是一幅扁平风格的矢量插画:浅蓝色背景,底部有一条浅绿色的地面带。画面中央有一只白色的鸟,身体是椭圆形,头部是小圆形,有黑色眼睛和长长的黄橙色喙。它骑在一辆黑色车架的自行车上,自行车有两个带辐条的深灰色车轮。鸟的一只白色翅膀向后伸,另一只向前伸到车把上,橙色的细腿向下伸到踏板上,车把附近有一个小小的黄色圆点。

Wings on the handlebars and feet on the pedals make the pose work, but there's no saddle, the frame is crude and the pelican features are a bit weak.

The most complete riding pose, with wings holding the handlebars too, but the bird is too round and its beak a bit short, so it doesn't look much like a pelican.
