8"x6" (about 20x15 cm) on a panel
I went back to my favored palette of ultramarine, yellow ochre, burnt sienna, and titanium white. I used M Graham's fast dry titanium white and walnut alkyd medium, which helped the paint dry quickly for layering brushstrokes and detail accents.
In the original photo there's a small train coming into the scene on some tracks but I left it out.
Here's a closeup of the water to see how the brushstrokes work. The lower right corner of the painting is where I actually started.
