Hmm... I see what you mean about the railing - I can squash 'em down a bit to make them more manageable to the eye. The lower (flat) part of the railing could be made translucent (about what glass would look like), which would keep them subdued, and would also help camoflage the back walls a bit for the renders (the back wall will prolly be flat with door/window textures + a bump map to make it look like a real wall w/ doors and windows, so that they can be changed or modified to suit the artist's wants without hosing up the rest of the structure.) Speaking of back walls, each back wall will probably be a seperate .obj file, as well as the elevator car, counters, benches, chandelier(s), etc. That way, the whole thing is more flexible. Same story with the roof (a vaulted arch which can be removed to make it an outdoor atrium...?) The rise on the stairs would be a bit more tricky at this stage, since they were the starting point for the rest of the room, and changing them would require modification of everything that touches them. With the right texture, I think I can minimize the appearance of height (something that gives the impression of an "overhang" when seen from the front, perhaps?)
