Montage #2

In this Montage I am trying to show some of the main historical sites of Austria, Switzerland, Italy, and France. I think i did a lot better job with this montage then the first one. I took more time finding pictures, and picking the right picture for the place it was going to be placed! I think I did a really good job with lightining the opasity levels. Now that im really looking at the picture, i think i should have made the flags go off the edges everywhere, but im not sure. What do you think? What do you think of this montage overall? What should have i done diffrent?
