Very neat riveting on those floor plates! I think I might be tempted to add some more detailing to the top to provide a bit more for the eye on the outside, maybe some search lights at each corner? Not quite sure yet how you'd scratchbuild those.
Thanks Eric and Slaves to Darkness,
I used up all my searchlights, but I think I have some of the building lights I used on the tops of some of the previous structures...I also could use more old Christmas lights.
Another small one to be a platform between bridges.
