Third image in the first post immidiatly reminded me of the Blacksmith character in the Unity Blacksmith Demo for Unity 5
Yes, you're not the first who points out the similarities with Blacksmith. But actually we developed this character (btw his name is Dorpkhal the Reaper) and in his first editions he looked completely different. As for me personally, I rather would put him on one desk with Clive Barker's Cenobites than with Unity's Blacksmith )
Okay... well, I don't see the cenobites in him as his character lacks all the defining aspects save the unhealthy skin color. No mutilations, no black leather religious/butcher clothing, no SM shenigans.
While the blacksmith has similar outer appeareance, and also a very ambigious personality (granted, this was the intent with the cenobites, but the whole SM thing and overuse of the word Hell and how society treats these things morality wise kinda destroyed all the "moral ambigious" vibes Barker was going for).
Just watching the blacksmith demo makes it clear its not a good guy, while at the same time not really painting him as a monster, given the adventurers who seem to attack him in large numbers are the ones doing the attacking.
That is how this character looks. Not really evil, but not good either. Somehow godlike, removed from the mortal realm. If that was the tone you were aiming for, good job!
Of the bunch, I really like this character the most.
