personally, I think the afghan girl is rather plain - and I'm afghan.
there are alot more beautiful & striking people.... but it seems like the west is only hung up on her (although I feel for her story greatly)
here are a few more Afghans (who are central asians).
and kindly don't speculate on who's a pashtun, tajik or hazara. the ethnic groups are vast (pashtun, Kyrgyz, hazara, tajik, uzbek, turkmen, baluch, fariswan, aimaq, nuristani, pashai, kazak, etc) stemming from greek, persian, turkic and mongol stock, and yea, they intermarry, etc. there's no stereotypical look for an afghan, and all ethnic groups "stereotype" is really broad.
