I am always fascinated by basing, so it would be very much appreciated to know how you got that excellent texture and the colours you used.
Texture: My standard basing mix. Polyfilla, water and sharp sand. Built up in layers. (I keep it mixed in a jar.) The Rocks at the back of the base - just greenstuff.
Colours used: Light sand - lot of yellow in it. Minipaints. Washed with cheap acrylic paint dark brown. Drybrushed the sand clour, then Ivory. I allow everything to completely dry. The wash, for example. I will do that at the end of a painting session so the base is not touched until the following day.
Static grass applied last.
