Thanks, Kalypso,

I am new to this and am a bit mystified by the whole cloning and photoshopping aspect of 3D art. In the first image of the girl sitting, the fusion seems seamless, and you see the same spread out toe shape in the other shots where there is perhaps less postwork. I never saw V4 toes spread out like that, and a skin that had such detail of veins and muscles around the ankle area. Many thanks for the links and I'll take a look!
