Sure!
Here's a pic of the unpainted bases. They are made of milliput with varius plastic bits in. When dry, i glued sand on (several layers).
I painted the sand P3 Hammerfall Khaki and the metal P3 Pig Iron.
Then the whole thing got a generous GW Devlan Mud wash, when dry i gave the metal a GW Badab black wash. After they had dried again, i gave the metal some VERY thinned down P3 bloodstone where i wanted it to look rusty. I gave the sand spots too, so it looks like rust on the ground. Drying again at this step. Then i used just a little pigment soot and rust.. then dry again
I finished the painting with a P3 Khaki drybrush and very light P3 Jack Bone drybush.
Last step was dullcote and glueing grass turfts on (from the trainhobby store)
