I look at trees a lot. Those that live near my home, particularly close to a window, become familiar very dear with time. They seem unchanging but they do change a little bit every day, just like us.
For almost ten years, I gazed at this linden tree outside my studio window. In summer, his flowers would perfume the garden and in winter, his large branches laden with snow were majestic.
Here it is in a sketch, done one April day at the very beginning of spring.
