I'm with the following comments:
"I hadn't noticed, and the provided image didn't sway me."
"If that's your example of a masculine looking woman, I'm with it."
"Oh christ, here we go. Not another one of these guys."
Yes, all this.
That said, all the Caucasian female heads do have a sort of chiseled Northern European look to them. I wouldn't say they look masculine, but some with narrower jawlines, softer features, and larger eyes would be nice. Also, some with a more Mediterranean or Middle Eastern look would be nice.
In other words, more variety and just more in general would be good.
