Ok, I don't have any pics of new construction, since I'm still working on them... but, just for reference, here's a few from before the shutdown, so no access to the cool new parts, or new attachment options, just old school stacking.
Some shots of Imperius Legionari's Roman palace (currently being completely remodeled, since there's actual Roman pieces now :)
Entrance portal
Senate chamber
Fireplace/Hearth
Underground lake. Can't see it real great... it looked cool in person though.
Teleporter hall
Hidden theater room (I loved hiding rooms with secret entrances)
Gladiator arena, sat just under 1000 people
Another view
Imperius Throne, secret entrance behind the fire wall
And a little from the Society of Salvation base
Entry elevators
Hallway leading to med center
Teleporters
Library
Pool room. Never finished this one...
I know I've got more somehwere, think they're on a different computer though.
