SHE WANTS THE 3D

[alexmach1]

I only know 3ds max, but an easy way to UV unwrap while preventing stretching is to apply a checkerboard pattern(16x16 or 32x32 squares usually work best) and see where squares get deformed/stretched. the squares highlight pretty much any UV error and works very well.

for faces with a single/solid color(ala the eyebrows of the second picture) UVs can be set to a very tiny scale to only take up 1 pixel to save space.
