I like the models, but the thing that really sells it is the nice lighting and very crisp looking texturing.

With the the large floor tile pieces you have to be careful because it takes fewer of them before it starts looking very repetitive (as in a copied texture). There are is a minor issue with the seams where the modular pieces go together, in the straight pieces the tile grooves get a bit tight looking in comparison to the rest of the texture (r in some cases blend in), and with the diagonal corner pieces the tiles blend into kind of unrealistic tile shapes. That said I don't think it's really very noticeable or ultimately really that important, and wouldn't really affect anyone using these models. I've seen far more egregious fudging in big budget CGI.
