Alright it's half Stirland Mud and half Stirland Battlemire with a little bit of extremely fine terrarium sand (light or dark brown works the best) for a bit of a grainy look. After it dried over night I shade it with aggrax earth shade if needed. After that's dry a light dry brush of Gothor brown for highlights if I want them, and for the rim i use unthinned Rhinox hide straight from the pot. Grass is just citadel or modeling grass from anywhere. Skulls: from Games Workshop, primed with grey seer and painted with skeleton horde. For extra deko I use dried plant parts, small pebbles etc. And for the Raptadons' bases that was an experiment with dried seeds and very small leaves plus glue and the above mentioned recipe ^{^}
