I'm very happy with how a lot of it turned out, but some things about it still look off to me. Maybe its the detail size? or the colors? Bold advice and harsh criticism is highly welcome.
Also, how do you plan stations? make room for big turrets? etc... I have to draw it out completely or else it looks like a splatter of mismatched rooms.
First of all the red somewhat stands out too much. The rest of the station is industrial themed and grey, so the red is like the color scheme in Mirrors Edge (the game used many white and vibrant full-colors to signify level relevant objects and gave advice via coloring).
You can make it orange, or change the beams into a greyscale or black with sparcely placed red dots. The other way is to place other objects in orange (not red), yellow or even a blue-hue around the station, like a docked ship or a docked container. Or an antenna. Lights, either hidden or some sort of streetlamps, could also help to make it more colorfull. It seems a bit dark and too grey for me. Even if its supposed to be grey, you can use more greyscales and some black too.
I would also add some round ventilation shafts on the outside, or something that cuts away the blocky arrangement of the 4 containers. It seems somewhat flat on many spaces, because the details are the beams and the front antennas and they are too far away from the flat cubes.
Lastly: it is a very nice work non the less. And I admire the effort you put into it.
When I planned big objects, I allways make a list of purposes and in what rooms they shall be met. Simmultanously I either lay out a floorplan or a scratch of the outside if I want a certain object. I also leave 2 rooms empty for later ideas. I focus on walking roads or connection floors as well on stations, and have some sort of lookoutpoints on the station. I also try to imagine how it feels to walk through the walkways between the rooms or hangars, and try to give nice view throughout those ways. But the first rule for walkways is having them efficient. They are important for me, because you don't visit rooms, the atmosphere comes from the walk and the stuff you see between them. Well thats how I play in Minecraft, and I just ported it for stations now.
