NURBs or Poly Head?
 

Okay so I have been messing around with a poly head tutorial (This tutorial)...and the whole time I am thinking to myself this would be so much easier as a nurb object. I want to make a realistic looking head (not cartoony) and maybe even a body eventually.

Thoughts? Tutorials? Suggestions?

Does it just take lots of practice?

Okay maybe someone can answer this for me about a poly head.

Once you make the poly head and you go Polygon>Smooth...is there anyway to go back to the polygon look? I tried going triangulate and quad but it didnt give me what I wanted, although it was better than the smooth vertix mode (yikes).

only if you saved your history can you go back.
