Just an opinion here, but the skin on the right side of the above image is terrible. That is a good texture map there (which one is it please?) Most texture maps are too orange (as in Fake Tanner Orange!!!!), or a bizarre yellowish greenish color. I do a lot of correcting of skin maps before I used them for render. And yes, this is a gripe of mine, the orange skin. I was once a cosmetic manager for a drug store chain and every summer I was required to push sunless tanners and all these products do is turn the skin orange. It's not a good color. I have had to mess with colors on so many maps to get close to the color of the map you referenced!
