After the model was painted I made the base from plastic card cut to size then primed with the grey followed by a coat of dark brown paint. I then painted the base with white glue and added ground black pepper, when that was dry I added a few spots of white glue then added some oregano herbs for the final touch.
I like the natural effect of this combination and the fact that it requires no painting is a great advantage.
Here are the rest of the pictures.
