Three Headed Giant

My three head giant was meant to be a still model. But I have to say that if you're going to make a still, it should look as detailed as possible. This model lacks the amount of detail I was shooting for. The skin on the ears was suppose to be a semi-transparent red. I heard that there is this one material that gives the skin a more realistic texture. When light is applied to the skin, certain areas display a change in coloration. The center of an object would be opaque. However, the surrounding area would slowly descend to transparency.
I will post a link to this method when I find it.
