Here's an advanced render. The neck has been tweaked, added few skin details.
The texures is very advanced, so are the materials ad the light setup.
Zbrush rendering, compositing on background in photoshop.
Fx81, The base mesh is 244 quads (I remove one quad band on the unused part of the neck base), and at level 7, its nearly 1M.
The spherical eye (not really spherical after all my touchup), were done by projecting a sphere on the model.
