Going my own way
This project pretty much begun with me searching for reference pics of the cockpit. Comparing to the Lambda-class shuttle cockpits in the movie this model has surprisingly few details in common, and I certainly wasn't going to go down the road of insane detailing. So I pulled a decision from my sleeve to use few colours for the buttons and displays (black, white, red, metal) even if a couple more would've been at home there (that meant I skipped a terminal-green and blue).The basic bits
I started my detailing process by applying dark grey (still the same VMA 71123 USAF Dark Grey) to some of the surfaces that had gotten a bit too much overspray during the airbrushing sessions, such as the console panels. On the plain surfaces the very gentle hint of grey/white was just fine, as the overall look remained dark. While I was at it I also painted the frame edges where the viewport glass was going to be glued, as if it worked for airplanes, it was surely work here as well.To give this cockpit a bit more worn-in look I drybrushed some surfaces with Steel (VMA 71065), which I also used for some randomish bits on the outside of the cockpit and the hull itself. The most noticeable marks of wear and tear I made on the door panels and the ramp in front of it. Finally I did a very gentle drybrushing of Steel on all the buttons, switches and displays.
Detailing
Both on the left and rights sides of the door was a set of lamps. In the Return of the Jedi they were a bit like blue WLAN signal strength markings. This model, on the other hand, had three light panels that I decided to drybrush with pure white (VMA 71001). My idea was that it'd look pretty nicely, but it wouldn't still be an attention-stealer.Then I kept on applying white drybrushing over the buttons, because in my world just about all of them were going to be like that. For a short moment I was thinking if the light panels should later be treated with a satin or gloss varnish, but most likely they'd look more wet than shiny.
Now it was the turn of the displays and the things that looked like good old-fashioned dials on the dashboard to get black (VGC 72051). I decided that the plain black was going to be only a very limited thing and in very tightly contained number of things in the cockpit itself.
Next I returned with the white paint to add detailing to the displays I had just given a black backdrop. Both the pilot and the copilot (I was assuming) had somethingthat looked like a <= 14" CRT display in front of them. The leftmost one got a series of dotty rows to represent lines of text as an idea of a text-based status information or a system log, whatever they were reading from their MFD. To the rightmost one I tried to paint some kind of a X/Y axis for coordinates, for example.
Finally I took a bit of red (VMA 71085 Ferrari Red) and touched up a few buttons and button-like protrusions. Some of them were lonely and some were in small groups. What were they all about? I hadn't got a clue, some may have been "don't touch this self destruction thing accidentally!" kind of warning colours, some "this is important, so it's clearly highlighted" and so on. As I had thought before, maybe some keys could've been painted green and blue, without looking out of place, but at this stage I didn't feel the need for it.
Reinstalling the seats
As soon as these things were done for the cockpit, I glued the seats back in. Back in the day I had painted them, maybe according to the instructions, maybe because I just felt like it, with plain brown on the cushionage and lightish grey on the edges and backs. The contrast was strong and it looked kinda silly to me.Now I repainted them with the dark grey (VMA 71123). Thanks to the overspraying effect I mentioned above, they were now clearly darker than the floor but not outrageously so. The seating part (the cushionlike part) I now painted flat black (VGC 72051). In my mind they now looked like a believable "metal frame with some sort of a disgustingly uncomfy vinyl-like padding" scenario.
