Hi, Maciej! His (or her?) look shows his reliance on you. "on the work" means this horse is not for a race but for riding, is that right?
This race Poland (malopolska). Appropriated to the work. In Poland still the horses on the street will pull vehicles. Works in agriculture, the plowing.These horses are strong. I love horses, I paint on the pictures. This will look on me because I am strange.
