I worked my way into the foreground, basically just refining areas. The reddish tree I made a little brighter and a little shorter and on the far right I added a deep shadow which I felt the painting needed for balance. In the foreground grass, I added a few highlights and shadows to define the area more.
Where I accentuated some of the trees, I painted corresponding reflections in the water near the towpath.
As the painting nears completion, I am debating about whether to add some people in the far distance. In my source photo, there are two cyclists in the distance who may be candidates.
