I like the building and bridge monuments but why not add some natural monuments? And since this a wish list, how about making them animated? I obviously think that the devs can do anything.

Yellowstone National Park with animated steam venting from fumeroles or just Old Faithful erupting occasionally
Niagara Falls with Animated water
Aurora Borealis; The Northern Lights could be an colorful animated shimmer over a forest
The Matterhorn, Switzerland in winter with snow billowing off the mountain
The Great Barrier Reef with animated water and fish swimming in the bright coral reef
