Summing all 3 pages so far for Square Enix:

1) Some people wish their eyebrows where thicker, some people wish they were thinner.
2) Some people wish their eyebrows had more color, some people wish they had less color.

I say, there should just be more eyebrow options to let us control thickness AND color.
For example, someone might want a blonde character with black eyebrows, but other might want a blonde character with yellow eyebrows.

Just give us the option to choose what we want.
