The giant walking baby-faced statue is completed!
The servitors head is a green stuff cast of a baby dolls face, and the legs are from a Chaos Defiler. I really enjoyed painting this model, since I could experiment a lot with glazes and washes on the metals to give the different plates a slight variation in colour.
I have not yet decided what this model is supposed to represent. But I'm picturing this thing wandering aimlessly through the ash-wastes, so I don't really think it needs another purpose than looking creepy. The pipes sticking out of the machines mouth is the host of a Genestealer spore-hive. The Cult uses this creation, and many like it, to spread spores and Tyranid bio-gasses into the planets atmosphere in preparation for the Tyranid invasion to come.
