Obviously I'm not getting the same impression looking at her and actually those pixels are not supposed to be brows (but it may pretty well be you're right). All I can say is that it's NOT supposed to be the average cute little girl, fitting the overall mood of game (which isn't really there yet).
Just to clarify, this is the impression I get when looking at her face:

Again, I'm not meaning to offend. It's just the way I see it. It could very well be just me, you know, like one of those two faces/vase optical illusions or something.
When the pixels are zoomed way in like that though, the old-man illusion sort of loses it's effect on me, and it does look more like a girl. It's just the small version that makes me think "old man." Or maybe "old Russian woman."
