I dislike the low hairlines on the basic Viera styles. It looks off to me, and pushed me away from picking the style I otherwise would have used.

Roegadyn seem to have the same issue, though I can't recall noticing it on other races.

I'm not sure if it's a particular artist's work, or a deliberate choice, or just trying to cram too much detail into the shape of the hair at the expense of it ending up bigger than it should.
