Very nice! I like it! As for the two turbolift shafts hanging out there - those are just for neck passthrough, right? And the three hallways that deadend in the center portion - are those to the outer hull access, or something else? And the extra hallway? And the four areas around the saucer's edge - are those lounges?
Likely simple questions, but I'm just having a hard time placing those bits in the grand scheme of the ship. You're doing great work on the ship.
