I added another layer of celluclay to the base where the road will be. The earth areas were then primed using Vallejo US Field Drab, and then washed and colored using different oils (light mud, dark mud, industrial earth). The small stones are painted in a light grey color, and also washed using oils. The gras was primed with the airbrush, but it has to become brighter and more colorful. This is how the base looks like now:
On the side of the road there will also be a signpost, which was inspired by an original picture from a Russian road. The post is made from a wooden stick, that I have treated with a wire brush to achieve a rough surface texture. It was then painted using different Vallejo acrylics (beige brown, German camo black brown, deck tan, medium grey), and finally washed using some oils (black, burnt umber).
The signs are made from sheet styrene, and will be labeled with self made decals (I spent quite some time looking for a nice cyrillic font…). The following pictures show the parts of the signpost:
