A picture painted by light

A very warm afternoon that I almost fell asleep in the van. The shadow casted by the trees on the grass with the texture of the tree has created a beautiful picture. I sketched this and see if I can paint it in watercolour later.

很熱的下午，我在車箱內差點睡著。看到草地上的樹影晃動，跟樹龫上的紋理形地了一幅美麗的圖畫。我把它速寫下來，或許會是個水彩畫的題材。
