我把樹冠視為一片可流動的地形：用層層半透明的綠塑形葉海，以深色枝條標記方向，再留出潔白的負空間做成“風路”。鳥只是路過，但速度與自由感由此被看見。

I treated the canopy as moving terrain: stacked translucent greens form a leaf-sea, dark branches mark direction, and clean negative space becomes a “wind lane.” The bird merely passes through—its speed and freedom made visible by the path of air.
