The hard stuff --- almost done with this painting

I've painted water and rocks for myself or to help students with their work and I've always thought they are hard to make look convincing. Using a combination of brushwork and knifework was the way I did the rocks in the foreground. The water still needs to be finished, especially what's flowing over the footbridge. This is a 20" x 24" oil on canvas of a creek or stream going through an area near the Georgia border in North Carolina. There is a house to the right not in the picture and the water is quite high flowing over the bridge. I had a lot of work finishing the numerous trees in the background. It's a fun painting which I look forward to working on each day.
