Oh, okay, will add the wall below bunk. Well, from the photos that i got on the internet, captain bunk is closed up solid below. No lockers, not a thing, just wooden paneling. Technically i could add lockers below too, but there is no way that those would be visible from any angle, well except if i add mirrors
i made some snapshots how i made the tanks, probably a bit artistic, but in my opinion could trick the eye. there are subliminal indentations in the walls (0.15mm) and 0.3 also in the bottom. I "etched" the bottom a bit more since it is thicker, and i guess it will be better ratio with sligthly higher indentation. There are a lot of helping lines still visible, just ignore them. Once in a while i sort them out and assign them a proper layer
Also the floor of freshwater tank could not be rendered blue, since it is integrated into the main floor, so the whole thing would turn out blue, but it will be painted blue on assembly
