Very nice work, especially that last render- I love the cold light; as Remus said earlier it's very reminiscent of Herzog & de Meuron's Tate Modern or at least it portrays very well the use and feel of concrete and hard materials combined with fluorescent strip lighting. Only criticisms would be that it'd be good to see a few more people dotted around just to make it look a bit more popular and you should reduce the scale of that texture on the concrete columns and beams about 50%- it looks like spray-on foam fire proofing at the moment.
I'm curious- what render engines did you use? Irradiance Map primary with Deterministic Quasi-Monte Carlo secondary? The results are excellent but the render time seems very long- perhaps the culprit is the glass doors if they are double-sided with "genuine" refraction? I workaround this by using a zero refraction glass material for the front and back faces of glass and a separate dark green zero refraction glass material for the edges- the results aren't as accurate as yours, but it decreases the render times enormously.Table 1.jpg
