behind the walls?

The City of Seoul

I was interested in the City of Seoul. I decided to observe 

the City from far distance. The city was crowded by small, 

big, large buildings and it was surrounded by mountains.

because of the mountains the city was like it's under the 

Dom/protection so I tried to simplify the view of our city 

under the Dom.

Simplified City under the Dom

After my trial to get rid of all the building, I got this sketch 

of my imagination "Simplified city under the Dom"
