Hi,
I decided to make 4 islands for the head: top, face and each side. I will see if it was a good idea.
[Edit (Updated Mon Jan 08 2018 11:21): my bad, it is actually neck instead of top, so the 4 islands are Face, Neck, Left and Right side.]
Here is the Unwrap:
Should I have applied a Smooth vertex or a simple subdivision? Not sure yet, but my mesh is quite …
… angular.
Also, magic tool for you guys: Ctrl + RMB in edit mode, also called shortest path selection , check this : https://docs.blender.org/manual/en/dev/modeling/meshes/selecting/advanced.html#shortest-path
Cheers !
