Gigaroc, Not sure what V_V means. No that's an understatement, I haven't a clue what it means. The overall effect is good, with no nasty Poser edge shading problems. Is it intentional that one of the openings seems to have a vertically sliding door partially open? Similarly, the two upper bits in the rear view are different. Is this intentional? The light grey shaded bit in the left hand upper bit doesn't seem to line up with the supposedly vertically sliding door. The vertical parts of the railings seem a bit too substantial (ie make them thinner) and I would expect them to be set back a couple of inches from the edge of the platform. It's not good engineering practice to have them glued to the outside face of the platform. They appear to be about 4 in width (100mm)in the x direction but of zero thickness in the z direction. This is unlikely. They are there, I assume, to stop people falling to their deaths when leaning on the railings. They therefore need to be stronger in the z direction than in the x direction. To comply with British building regulations the gaps between the vertical railings should be sufficiently close together to prevent a 150mm diameter sphere (about 6 ins) passing between them. Thanks for telling us that the grey things are gates. Unfortunately everything is a shade of grey of one sort or another! :-) It would help us to be more constructive if we knew what sort of building it was meant to be. At the very least, is it neolitiic, Roman, mediaeval, contemporary, futuristic, eastern, western or whatever? Better still, is it a prison, a castle, a brothel, a church a theatre, a cargo depot, a night club, a DIY super-store, a dog racing track, a police station, a multi screen cinema, a brewery, a pub, a school, or a Martian space station?
