Shot this at a small ghost town in Calif. a few years back. Not sure if it works but thought it was a bit different.
Converted in Silver FX, selected an area and applied a sepia tone.
Dave, for me, the silver area is too contrasting to the warmth of the sepia. Did you consider adding just a very light hint of sepia to the back grasses? I love the composition on this, though - your eye goes in from the side of the house and gets one-two punched by all that's going on. GREAT angles!!!
