I would say that sheep on the endless grass are grazing with their heads down. What is the sentence behind a good horse?

I will say: endless grassland, snow-white sheep, steeds grazing with their heads down, tall snow-capped mountains in the distance and white clouds in the blue sky depict a harmonious and beautiful grassland landscape.

Lush, tall and straight trees, tinkling mountain springs and singing birds in the forest constitute charming mountain scenery.
