For an unfinished ship, this certainly has much polish. It could use a complete systems gutting and reconfiguration for the new power systems, and probably for the upcoming weapon system changes, but otherwise looks complete to me! The central forward section has a great deal of unused space that could easily be assigned to house a sizeable reactor with stabilizers and chambers. You could even position stablizers in some of the more distant sections without too much fuss, but generally I just see it as an excuse to expand and embellish the engineering section.
I know from reading your earlier post that you seem to have some anxiety of deciding whether the ship is done, whether you should keep tweaking it, if it is optimally detailed. Honestly, you've done a great job so far and I think that you just need to decide that it is a finished project visually and setup the working parts so it is actually complete and functional. A wise man once said, "Great films are never completed; they are merely abandoned." You could keep working on this forever. Maybe instead start thinking about other vessels in its production family?
Specifically, I recommend making the airlocks in the aft section USD compliant and labeling them as Port, Starboard, EVA, and also labeling the hatch leading to the dorsal corridor. Maybe she also needs a shuttle or a few escape pods.
