Hello pixelation.
I haven't really posted on this forum except for the Secret Santa and Hexquisite collab.
Decided to give a try running a topic with the machine city.
Here's how it looks right now:

And this is first more or less detailed draft:

Originally it had less open space and more buildings, but it felt wrong somehow.
I guess I should put the story of the city in here.
WARNING: following text contains poorly written sci-fi.
This city is actually a giant computer, a size of a city (25-30 km in diameter, depending on the side you measure from). It was built some years ago, but then funding was cut and all the research planned weren't realised.
It's hermetically sealed at about 200 meters in depth, so noone can get inside manually, even rats or cockroaches, not to say about people.
And for humans even those 200 meters are hard to pass since there are lots of pipes, wires and metal plates on the way.
But they've learned to get incide via special ports (like the Ш-3/Ш-4 thing on the picture - a places that have a connection with inner parts of the city) using computers. Or laptops. Or any other device they could pass the security systems with. They haven't found much information and mostly do it for a hobby (like people who go to abandoned places).
So, here it is. What are your thoughts and suggestions?
