Front Steps Texture Mapping

As I said in my previous post, I had to re-model the stairs to make the texture mapping easier, especially in the grout. Here's the revised geometry:
And the UV layout:
As I did with the brick facade, I kept all the UVs in the first half of the quadrant so I could create a 1:2 width:height texture map.

Here are the color, bump and spec maps:
I created the bump and spec using Color Range selections and various adjustment layers. I'm very happy with the final result.
