Easing my way back into using Blender, because I want to create a few more details for the city, next.
So, for starters, I have just taken a few of the things I've already had and remixed them a bit: I've added a few details to the roofs of the brick buildings to make them less empty, and put together smaller versions of the satellite dishes and cell towers, to attach to buildings.
What I really want to get started on are these things, though:

Marquises and signage! I think these will add a lot of life, to the city.
This is a sneak peek, because I'm sure this is going to take me a while to actually finish: I need to build up some speed first, and the hot weather is really tanking my productivity, currently, heh.
Really, there's still so many details I want to add to the city: Bus stops, street signs, dumpsters/containers, trees,...
Now is probably a strategically good time to take care of at least some of these, before I stumble into the next big code topic.
