The hillside behind the track naturally needs some more scenicking, besides the basic tan paint it has gotten already. I though it would be fun with a sort of small landslide, where sand and garvel have skid down the hillside, making a scar in the terrain.
This was very much about forming the edge left in the dirt at the point where the slide begun.
I started by pinning down a piece of string as shown below.
Next I leveled the terrain with the string using a sand spackling compound (putty). I did this on the upper side of the string only, creating a distinct shift in terrain level, like this:
When the putty had set I gently removed the string, leaving a kind of sloping terrace.
I painted the putty with the same tan latex paint I earlier used on the hill side.
I then scenicked the area with various material as static grass, sand and pieces of gravel. I used grass above the slide and on the sides of it, where the terrain was untouched by the slide. The slide itself is natural sand and gravel, with finer sand further up and larger pieces further down.
Here is the result:
