Still working from top to bottom, I now am able to paint the water reflecting the sky. I have made several stabs at this and made a muddy mess. I'll have to wait until it's dry to clean it up.
For the stony bank in the foreground, I laid in a medium toned gray made with the same cobalt blue and cadmium red light mixture. I then came back on top of that with a lighter tone to suggest the larger stones. That was fun! I added some darker notes and some lighter ones. I'll get to the bushy grasses later.
At this point, I can stand back from the painting and get a general idea of what the final picture will be. I squint at it and look at it in a mirror. The good news is that I like the way it is going.
