Once the 'wash' was fully dry, I started to paint some of the details: the chimney, the porch, the windows, and the notice board. The red bricks were painted individually with various GW and Vallejo acrylics, which were 'wet-mixed' on the building (a delicate job but well worth it, as the white mortar shows up so well).
As above, showing the individual chimney bricks being painted.
While painting the chimney, I mixed up various natural tones for the stones in the base and lower fireplace area. The mix was random, but keeping the paint mix very watery and allowing the color to be built up gradually. This process took some time, but I wanted the finish to look as natural as possible. A simpler (and quicker) technique would have been to drybrush the colors over a black basecoat.
The same stage of painting, but featuring the brick/stone chimney in greater detail.
The roof was first painted charcoal grey, and then 'washed' with a diluted black wash. Once dry, lighter grey drybrushing brought out the detail.
