BengalTiger: The existing dock section could probably be used well with the Modular Construction Kit, so there's not much need for a dedicated new section.
AndrewofDoom: You could make a tall one by overusing the section that connects two different rings, I suppose, but small, circular stations are really what I have in mind here. (Besides, I might make a larger, more versatile modular station at some point, because we're sorely lacking in good large stations!)
Anywho, I finished four more sections (two textures): the dock section, the "hub" section that connects the ring to the center, the residential section, and the sensor suite.
Dock and hub sections (and filler sections, since too many dock sections gets crowded):

p3d.in!I still have the texture for both center sections left to finish, and then debris/LODs/miscellaneous POF stuff.
