Ever since seeing Star Wars, I've loved the image of some giant beast's bony remains bleaching in the sun. This was a particularly bony Spawn toy that I dismembered and embellished in a fashion typical of much of my smaller chaos scenery. I usually start with some wandering spiders, using a mixture of plastic novelty spiders and the nice Warhammer Quest plastic ones. Then I mount the main component onto a small piece of pressboard with superglue. Then,I glued some sand on with white glue, and superglue on discarded weapons, bones from plastic skeleton horses, the odd skull, Bits of armor, and anything else that looks unpleasant (the Chaos Warrior regiment is a good source for bits, by the way!). I spray paint the whole piece white, then use a brown wash on all the bony bits. I then paint the sand black, and paint any weapons or armor in suitable chaos colors. Finally I drybrush the whole piece with white to get good contrast.
A back shot of my Khorne chaos temple. The columns are from wedding cake, and are adorned with plastic skulls from halloween novelty rings. I used jewelry chain to hang icons and skeletons from the ceiling. I used epoxy putty to make the flagstones. Ribbed wire sheath trims the roof and base. The Warhammer quest arches make nice chaos scenery too- that's one in the foreground.
Here's a closeup of the Blood Throne in the middle. I used the lower jaw off of a skeletal horse toy to make the back. The seat is made of a skeleton rib cage, partially immersed in red wax. I coated the wax with a layer of gloss red paint to get the bloody look.
