The car in the first two renders is too shiny. But aside from that, it's a very impressive city. I wonder if he modeled the whole city or is using clipping planes.
The trees too interest me a lot. How did he create the foliage geometry? And how did he make so many trees. I wonder if he has a script to generate trees that are unique to one another and give each tree, each branch it's own character. This is a enormous project to lay out each individual piece.
Did he model each support column? Or is he emulating the look with trick maps?
This is intriguing.
