Thanks Byron. A brief PP explanation can be found here, just scroll down to post #9. Lately I have been adding layer masks and blending modes to my workflow and it is a bit complicated to explain, but I will share it when refine the flow.
The pano shot is composed of 4 RAW files stitched together by Photomerge in Photoshop CS. The grey color was enhanced through burning, and it helped that the wall was a bit grey to begin with and it was shot during a rainy day. Thanks for looking!
