After some considerable tooing and frooing, the test model for the cult is done. Trying to marry the aesthetics of the Adeptus Mechanicus and a genestealer cult took some mulling, but I think I have a reasonable handle on it. Essentially whenever I come across a stumbling block I'll just refer to one of my Giger art books. Job done.
The paint scheme came together once I lightened the skin, going much paler than originally anticipated. I did consider making it a much cooler tone, shading with blues and purples, but the fleshier shading sits better I think. The base is pretty neutral, which is as well considering the amount of colours in the scheme.
Here's some more views of our neophyte and his late grandad.
Next up will be some of his squad, including a particularly hulking 2nd gen special weapon carrier.
