7.25

What the judge sees: Original (Chinese) 这是一幅扁平风格的卡通插画,画中一只白色的鸟骑在一辆红色车架的自行车上。鸟有长脖子、黑色小眼睛,还有一张朝右伸出的大号黄橙色喙,喙下带囊袋;身体是椭圆形,尾巴是三角形,一侧翅膀向前搭在黑色弯把手上,两条橙色细腿向下踩着黑色踏板。自行车有两个黑色轮胎,里面是灰色辐条,中间有一个深灰色圆形齿轮;背景上部是浅蓝色天空,底部是一条绿色地面。

Clear pelican features and a complete build, but the other leg is in the air and the chain is missing.

Easy to recognize as a pelican, but only one foot is on a pedal and the frame proportions look a bit odd.
