How long did it take to concept and put it all out?

Assuming mars' core isn't alive:

Btw for a futuristic look based on mars, you want to take in the fact that mars is farther from earth, so how are they getting heating.

Most people make futuristic building white, idky they do, but if mars were to have white buildings it would be even colder and even more uninhabitable, Black/white buildings would be far more interesting and realistic because Black absorbs and holds more heat, Mars in order to survive without a living core like earths would need a lot more surface heat in order to maintain life.

Also if the core isn't alive, bye bye civilization, hello radiation and solar winds.



Btw, great concept, really beautiful.
