I love this idea!! Never even entered my mind. It will be a long minute before I ever have enough buildings for something like this, but I love building my city nonetheless 
Most of these Players have been working on these for Years. Building a Little Regularly will get you there! I LOVE seeing the Imagination of some of these Amazing PPL. 
The art city’s show that with enough time and dedication, it can be more than just building your city. I can be your own special work of art.
The only thing I’m still trying to figure out is how to ‘stack’ my buildings like they have been able to do. Is it easy to do? What’s the trick?
YES! It is easy to Stack, But at the Level some of these Rise to is Very Complicated and Takes a Lot of Concetration! My Mind can not even Comprehend their Understanding of the CW City GRID and Their Ability to Manipulate it!
I Think it is a Super Talent and I LOVE SEEING IT, I also LOVE Showing Others what is POSSIBLE here on CW if you open your Mind and Participate!
I wish more Players would Post Cities they see that Deserve to be seen to Inspire US ALL, Here on this Topic. 
How do you take a screenshot of something and attach it to your post?
I use the Snipping Tool.
I would love to know how to as well (not saying I actually would)…I literally cannot figure it out!
wow wonderful art work, very creative
