I love this character; he's so nice and dark! This is Trystan for M4 with the Steel skin map, Wild Dreds for hair, a weapon from Deadly Edges and a loincloth I picked up at Runtime DNA, though I set the cloth to match Trystan's hair. Look at the definition in his arms. You can actually see veins!
After a while, I got the idea to try Trystan in a prone pose.
Then I hit pay dirt with this specific light and character when I took out the background props. Look at the richness from those shadows!
