Lately, I've been building a number of microscale ships, namely huge warships along the lines of Executor from StarWars. In my opinion, the best villain is the one who thinks s/he's the hero, so a ship of this sort shaped vaguely like a seraph was a goal of mine for a while. Not only are seraphim traditionally the highest class of angels, but Satan was also supposed to be a seraph originally. Seemed appropriate for the type.
I don't think this as well fits the theme of "really big ship", but it's cool enough that I don't care.
The place where the wings cross holds a hangar bay. And, yes, this part of the ship is somewhat inspired by the Leviathan from Knights of the Old Republic.
