The small changes include: adding a lecture theatre and library for the Praxis side (accessed via the main corridors on each level); an exercise area above those; two sets of toilet/wash room blocks on the Praxis side (which really did need to be near the accommodation areas; a simplification of the area near the state rooms, which is now level with those and the recreation area, and partly covered; drains!; the life boat now has a proper dock; the warehouse basement is a bit more regular now; and the recycling tanks are spaced properly.
The process of going through level by level is lengthy one, but it made sure that everything is in the right place, allowed me to eliminate multiple prims where only one was needed, and align walls and floors properly. The NEXT stage is to go though the layers again, adding signs, furniture and props. Once that's done BB sets can be created and the set will be complete. It's a lot of work.
