Incredible skin texture and tone, mesmerism eyes, deep shadows, like a dream with eyes wide open.
Does anybody could describe how to achieve this fantastic effect?

A photographer with some skill is always a good basis for this ;)

Seriosly, are we looking at the same picture? I can't see anything special about the skin, neither the shadows...

The eyes are obviously enhanced, basic stuff there, some color layers and an artificial catchlight. Anything else is just a matter of correct balancing of light and shadow.
