Death of Polydorus and Birth of Adonis (Cassone panels) Titian (Tiziano Vecellio) (1488/90-1576)

The picture has something of this: water, mammal, nature, tree, two, outdoors, lake, recreation, wildlife, river, bird, landscape, rock, people, park.
Perhaps it’s two paintings of a man and a woman in a landscape, one of which is falling off a tree, the other of which has fallen leaves.
