Many thanks for comments folks. It gives me a boost of encouragement at times when it feels I am stuck on how to do something.
Now we are getting into some small stuff. The front and rear wall of the hanger bay are all but complete. I only have 1 blurred screen capture of the front wall and relatively decent ones of the rear wall and part of the ceiling. So I have done a little ad-lib.
The walls are slide in plates made of 0.25mm sheet and the ribbing 0.75mm rods. What detail I could add was made from o.25 and 0.75mm bits of sheet left over from detailing the trench. The odd shaped lumps are made from the bottom of resin 1/35 scale U.S. style water jerry cans.
When looking at how the hanger was lit, I noticed a plate suspended from the ceiling, and the light source was projected from between the ceiling and the plate. That is why there are so many shadows in the hanger, there is no direct ligthing.
So I drilled a 5mm hole in the middle of the ceiling through which I will poke in a white LED.
Things may look a bit shoddy at the moment but once the walls are glued in place in the hanger painted, it should be a different story.
