They do lack some definition... I might 1) shadow the undersides of the robes, 2) add some trim, and 3) bruise up the visible skin, especially as they have steel rods forcibly inserted into their leg stumps... The pale robes are to give them a more medical look.
So, here's my Pariah Agent, Acolyte-Representative Uzziah Nagure, and his Servoskull body guard.



A
couple more.
He has another Servoskull companion, who speaks for him (as his face is a steel plate), but that's still pretty WIP.
Here's a pair of mercenary bodyguard/kidnappers/assassins, named Volo and Veres.
And Some More.
Here's my Sicarius Assassin, Number VII.

And Some more.
I sculpted the skull part of the head! The gun is from some WW2 german armoured car machine gun, a 50 calibre or something, with the thin part of the barrel cut off. He's a mix of Blanchian stuff, Tron, and MDK, so he has a head-gun and a grav chute.
Here's my new Trader's bodyguard, wearing a Lacrymole skull as a hat... He's in two pieces, as you can see. On his belt, as well as the daggers, he has a wrapped up dead rat (his lunch, I guess) and a bundle of bones on a string.



And here are some WIP mutants, to accompany various Chaos leaders (my two Astartes, or my Cultists, or perhaps my Renegade Inquisitor..._



And this doesn't include the new Daemonweapon Claw for my aforementioned Renegade Inquisitor, my slightly altered Emperor's Children Marine (new chest scars), my Slaanesh Cultist, my Vanus Assassin, my Harlequin, my Wych, my Crusader, my barbaric Rogue Trader, Inquisitor Lord Cass Mark V, my repainting of Inquisitor Adelmar, a new Techpriest... the list, obviously, goes on and on.
