First screenshot has a nice angle and is overall the best. From there on the quality decreases, the 4th being the worst. Horrible screenshot.
You should have just uploaded the first one and left out the others.
It doesn't look like everything ends suddenly in the first screenshot and you are not so upclose to the arch that it looks blurry. Where as in the second you see those hanging shrub things which looks horrible close up. In the third picture you see the sudden end of the river and picture all together, that doesn't look good. The 4th as mentioned earlier just has a bad angle making everything look bad.
