AR3NA redux - skin, first approach

This is a first approach with the skin surfacing. I'm using the new skin material from Modo 601 and I found it is not ready to use as expected. It's a good base to work with, but must to be adapted depending on the model you are working on [and the parameters to be tweaked are many]. Skin textures need to be improved, the model misses a normal map and the specularity has not yet been touched. Texturing with Modo and Photoshop.
