I decided to go with a quite pale skin colour, which tuned out quite nice. This is however a completely naked model, with very few details that are not part of the skin. To make it look more interesting I gave it some dots and veins. But I wasn't quite happy with the model until I gave it a base. This one has some extra details on the base, and more orange than the other members of the Cult. The orange on the base makes the model blend a lot better with the ones in orange clothing.
Bloodletters are one of my favourite GW kits. The legs and hunched forward torsos work great for all kinds on models. Here I have a couple of pictures of the same base model used in three different projects. They all even have arms from the fantasy Ghoul kit!
On the left I have a member of a radical Inquisitorial Warband. I'm not completely sure what this model is supposed to be. But the thought behind it is that he originally was a human, before the Inquisitor he serves had him turned into a monster.
In the middle is the Genestealer Hybrid. The Bloodletter is a perfect base model for a sneaky looking alien.
On the right is one of my Slaaneshi Brutes, that I made earlier this year.
Thanks for looking!
