Nice, mind if I give some critique?
The specular texture would work better with more contrast, A LOT more contrast. Really crank it up, it will make the shiny areas pop a lot more compared to the dull scratched areas. Even applying a bit of sharpening helps too.
When the spec texture has doesn't have enough contrast, the specular almost looks just like a flashlight. What you want to do is make a very obvious difference between shiny and dull areas. CoZ's screenshots are getting there,especially on the lower half of the wall where it looks like there is some depth because of the shiny/dull contrast.
