In any case: it´s dark there inside... so you don´t see so much of the details.
Before you add the little colums, it´s necessary to bring the floor in place and than place the colums on the floor.
The roof lights (the dark grey square with the two white stripes) need to be placed close to the back-wall (this part is a bit shorter than the depth of the roof).

I surely will have a problem later with an ugly space between the floor of the shuttlebay and the landing threshold outside the shuttlebay, because of the inner and outer door glued together in 190g paper. But I am sure there will be a solution, later...
