I noticed they were on average, not very attractive, but there would always be one really pretty one. I also noticed the pretty ones tended to be petite with round faces. The Japanese boys had the same ideas, in other words they thought the same ones were pretty that we did. The ugly ones were tall and had flat faces.
The girl who plays Lana Lang on "Smallville" is about as pretty as they get and she is Chinese and Dutch.
Over all I am certain the prettiest girls come from Ireland, Scotland as well as the rest of the British Isles. Also Denmark, Sweden, Norway, and Iceland.
I think beauty is mostly about regular features and for some reason, those places seem to produce the most like that.
I'm attracted to those too. Of course, I'm from there, lol.
Also think about how many popular actors/actresses over the years fit into this category...many had unusually large heads for their bodies (Jolson, Astaire, Bendix, Cary Grant are just a few that readily come to mind...)
