I have also added two pictures to the set LAND, and I'd like to comment them here.
When you drive along the Delta of river Ebro, you get used to the Horizon. Simply put, it is always there. After a while, you realize that only certain familiar references, like electric poles, help to determine the distance between places, and in which direction you are driving.
Somewhere in the middle of continental Greece, there's this castle on a tiny island, that is connected by a bridge to the coast. The city was built with the stones available in that area, and therefore, the island and the houses have the exact same color. But when the sun goes down (behind the city, in this picture), you can see the skyline of the half-demolished fortress and, on the background, the coast and the hills.
