Render Updates

This week I've been trying to add some grunge to the window frames because they were looking far too consistent, which is a bit difficult to avoid when there are so many of them. I added some textures to the stairs as well, which was a bit of a challenge because of the UV mapping involved with the large blocks that are next to the steps. In these renders, I had shut off the object layer containing objects from 2005 that were probably nonexistent in 1963 (black iron lattices along the windows, and gates on the sidewalk level.)
Here are some closer shots. The doors need better bump mapping because they're too similar to the large vertical outer door frames.I'm pretty happy with the base rock texture of the stairs, but the grout (yellowish areas) certainly need some fixing. They're too large and pop out, so they need some grunge on top of them too.
Here's a photo from 2005 for comparison.
