The Third Sheep

Often, I will plan to be at a certain place at sunrise in order to photograph with the warm sunrise light. However, on this particular day, the weather forecast called for cloudy and cold. So I did not leave my motel room until 7:30am and only then found that some sun was dodging through the cloud cover.
Looking at a map, I chose some back roads to explore. The first road followed a river, but I saw nothing that caught my photographic intentions. Then I drove off through some farmland and stumbled upon these sheep, grazing on a hillside covered with frost. Atop the hill, the sun was catching the orange leaves of autumn maple trees. At the bottom of the hill was a still pool catching reflections.
Just a bit of sunlight on the trees, combined with general cloud cover, the conditions were fleeting and did not last. I captured about a dozen images; this is one of my favorites.
Where is the third sheep? Uphill, further toward the trees, out of frame … but appears in the reflection.
