"Agricultural Implement & Paint Dealer" - Part 8 - Initial painting and terraforming

Got an initial coat of paint on the implement dealer this weekend, including a coat of paint on the raised seam roof.

Actually the roof got two coats of paint - the first, from Polly Scale Flat Aluminum, just lacked any life - looking more like a flat light gray. After that dried, I went back over the roof with a 50:50 mix of Vallejo "Steel" and "Silver," which produced a much better metal color. 
For the main walls I dry-brushed a coat of two craft paint colors - about two parts of one called Snow White (any "real" white would work) and one part of a very light cream (or off white) color called "Parchment." 
While that was drying, I cut a piece of 1" thick foamboard to fit between the front edge of the layout and roadbed, and carved it to shape. There's still some work to do here, but I did pose in the building in an approximate position. 

As you can tell from the overall shot of the building, the paint on the front wall needs another coat of white to even it out just a little. I think the effect came out pretty good on the side walls (see closeup photo to the right). My goal is a well-maintained, but weathered front wall, with the side walls showing more signs of wear and tear on the paint. 
The rear wall of the building was painted a barn red color (not shown), for some variety if nothing else. Frankly, the rear of the structure will likely end up almost completely obscured by brush and trees. 
I also made some progress on the Thresher's Mill diorama (I don't really consider these dioramas, but structure bases with a small amount of landscaping around the building itself, but that's a subject for another post. 
I'm getting ever closer to wrapping this seemingly never-ending project up!
