this is what I have been doing today I thought that it could be simpler and be more like the artist so I looked at that more.
Ive got to make all the shapes of the buildings and then make them more like buildings.
Background could have some more buildings smaller in the distance. silhouettes. And then maybe added glow to some of the reds looks like planets? add glow to the moon?
Some surface shaders some blinn? flat/3d.
I decided to start afresh
