While im thinking about it i might as well describe the way i painted the nids themselves. Their base coated white. then the flesh is painted red core. then given a wash of blood red, then highlighted and shaded with blazing orange then highlighted with fiery orange. This makes the skin really bright and rich with colour and also works well for making things like muscle bulges and the tendons stand out.
For the scale carapace i i painted scaly green, then working toward the back end of the scale, i gradiented in with goblin green, then scorpion green then sunburst yellow.
The mouth i painted black, the teeth i did bleached bone the tounge i did the underside liche purple the top i did enchanted blue. They claws i did with bleached bone, then around the flesh i washed in some snake bite leather, i then shadowed in the talons with some elf flesh.
The eyes i did simply chaos black then added one small spot of skull white in the corner, this gives them a really evil and alien look.
It a shame about my cam no being high enough resolution but as soon as i get a descent one, should be before the weekend i will post pictures of the hormagaunts, the termagants, the zoanthrope, and the warriors.
