Looked at all four. Very very awesome. Question though, was the [One-Texture] all inclusive to the objects in the scene as well, or just the floors, walls, etc.? Also will you be posting just a view of the textures or a side-by-side for comparison? I think it'd help give a better idea on how it was constructed. As a 3D artist myself (not that my profile here reflects that), I'd love to see it.
Yes, please post the textures and some wireframes if possible (I'm guessing it's high/higher poly to compensate for the lack of unique tex, but I'd for one would love to see it anyway). Looks amazing, the lighting is discreet and office like and the colors go well together creating a dynamic yet comfortable working space. Great job with the design!
