A woman in dark clothes sits in a chair, observing a rider on horseback in a large indoor arena. The rider is wearing a dark outfit and is actively guiding the horse across the sandy arena floor. There are small jumps set up. In the background, another person stands observing the horse and rider. The arena is well-lit by natural light coming through the roof. The ceiling structure is visible with a pattern of beams. The general atmosphere suggests a training or lesson environment.
