On the first one all I can see is a couple of lines but that's not uncommon... I am one lousy art critic.
The second one, especially if there is evidence of Roman ruins in the area, could certainly be an aqueduct. For the most part these were built below ground with the famous arched structures built only to cross valleys. The Romans were very precise. A photo taken of the inside of the "trench" should show even rows of masonry which would have been lined, probably with wood, which would long ago have rotted away.
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.
