Welcome to cooking with the Commander,
Take:
1 'nid Ravener body
1 Chaos spawn plastic 'mouth'
greenstuff to taste
6 pieces of wire
1 chaos spawn plastic tail
Mix em up a bit, drill and pin and you end up with quite a cool looking Cthulhuesque beastie:
Just in the base coat with a little highlighting, more paint to go on soon as!
Enjoy
The Commader.
