I finished one floor of the high-rise I’m modeling, so I rendered out a quick test with a bunch of the floors stacked on top of each other.  You can take a look at a much higher resolution image of the render by clicking on the image.

Part of the final building will actually look like this, but the top half of the building has a slightly different layout.  And, of course, I will need to setup texturing and shading.

In response to a comment from the previous post:  I am creating this in Maya.
