What the judge sees: Original (Chinese) 这是一幅扁平风格的卡通插画,画面中央是一只白色的鸟。它有圆圆的头、一只黑色小眼睛和一张又长又尖的橙色喙,身前有一只灰蓝色的翅膀,正站在一辆深色线条勾勒的自行车上。自行车有两个浅色的圆形车轮,车架是简单的直线,中间偏左的位置有一个黄色的小圆形链轮。背景是浅蓝色的天空,右上角有一个黄色的圆形太阳,下方是起伏的浅绿色草地,草地上有一条深绿色的曲线。

Bird is standing inside the frame instead of riding, with no pouch and messy frame lines that don't make sense.
