I've been working on my Soul Drinkers some more, although I havn't made the greatest of progress.
Still, I got one Assault Marine nearly done, hailing from Tellos' blood-soaked following. To those who havn't read the books, he's basically an Assault Marine who's fallen to Khorne, but hasn't realised it it yet.
I still need to finish up the blood on this guy, but so far I've been focusing on finding the right balance between him being blood-soaked, yet being able to distinguish Soul Drinker heraldry underneath.
There'll be another nine like him when he's finished, acting as Blood Claws in an allied Space Wolves detachment led by a Wolf Lord representing Tellos himself. I'm thinking of doing the Tellos conversion next, before finishing off his following, but I'm not sure yet.
