What do you mean by the aspect of the skin, Jo? I'm sure it can be a better by using the glass shader with subsurface scattering, but I didn't bother because of the distance.
Luvs; Steve is right, you can get a personal licence. And the group is Roman, so the guy can perfectly well get away with his tunic Indeed, the thing to do now is find nice (Roman) fabric designs/textures, and learn to make proper patterns, or find some on the web. And experiment more with the presets of fabrics (50 or so!), which names' puzzle me mostly.
I deliberately overdid the size of the sack he's carrying, to add some subtle humor. Probably his wife's wardrobe.
Here's close-up of the guy, with his new hairdo. No subsurface scattering, though.
