Just trying out a few different surface techniques. This is a V4 model. Anyone who works with V4 texture maps knows that there's seams between the chest and arms which make it basically impossible to match an intricate texture. Luckily, I wasn't trying to =D What I was working with here was specularity and specularity strength maps. The torso has a texture map, but the arms do not. The trick was to match the skin specularity of the face while also matching the pink color specularity across the arm seams. Sure, I could have made another texture map and specularity map for the arms...but I was more curious to see how a specularity strength map would work. I had my math screwed up on the first few tries...but I figured it out eventually =D
