Well, the obvious next step in adding yet more insane detail would be to have the little stick figures replaced by ones that are working on the equipment, walking from A to B, gazing at the stars, hiding from their bosses... 
Apart from that, it's difficult to see what would be "missing". Unless you want to tackle the Drexler idea of an ever-changing ship, and draw alternate warp core fits that slide and and out through the aft access ports, alternate weaponry for the berths that now hold phase cannon, and perhaps hints of that secondary hull installation Drexler dreamed up. Just in the form of "projected updates" or "past configurations", and not necessarily in any great detail.
