Well considering that and taking reference the original schematics, when luke is on the antenna the bottom of cloud city(the top from our pov) should be tilted and not straight ;)

Also also in some shots Cloud city seems to be a bit more squeezed compare the schematics. not a problem tho, it looks more good ;)

I wouldn't take this as an "original schematics", as for many things in star wars there never was any schematics made for cloud city, this drawing was made for a book "the essential guide to vehicles and vessels" so it's rather an illustration made to look like one but not really faithful to the original (those illustrators, however talented, can't afford to spend the time we fans spend on that kind of thing). So, generally speaking a lot of the blueprints in that book are not faithful to the original or simply wrong…
