Ok, this is my hour attempt.
I thought I'd start with a 10cmX10cm surface produced by freeform curve using control points at 1cm increments.


Then created a network surface using these curves.
I have a question about this surface, when I produced it I could see little white flicks through it, is this normal, is it the graphics or is this surface not a good surface, I have no analysis tools at the moment to check it.
on the other hand it did trim and join ok.


Then all I did was push 'n' pull the control points to produce this nose, it was quite entertaining and educational. added some nostrils and you have a basic shnoz.



I think with a little more refinement of the mesh and finer control points you could probably get more detail, but as you said Michael it is hard work.

Cheers
