The final Reverend Moira from the set is armed with a MULTI-Sniper Rifle.
The bases were constructed by smoothing out a lump of Green Stuff putty into shallow mounds on the bases. Silicone sculpting tools called "Color Shapers" were used to push some contours into the surface. Cracks and splits were added with a sharp X-Acto blade. When the GS had cured, sand from the beach was added, and the sculpted ground was hit with a little bit of fine sand texture medium.
The bases were painted with P3 Umbral Umber, then highlights were airbrushed with GW Dark Flesh, VGC Leather Brown <> GW Rotting Flesh. The whole thing was given a thinned glaze of Liquitex Transparent Raw Umber. When dry, the sand was drybrushed with Leather Brown <> Rotting Flesh.
