I was poking around pictures of Fairuza Balk and I noticed in this picture, she kinda reminds me of Dawn a bit: http://www.imdb.com/media/rm3831995136/nm0000103  (I hope you can see it)
I think Dawn also has a fairly big, sparkling smile aswell.


I also think that Allison Mack has a very slightly similar nose to Sarah Michelle Gellar: http://www.allison-mack.com/img/wallpaper/am_series_wallpaper_1024.jpg
Here's a comparison: http://www.rexwallpapers.com/images/wallpapers/celebs/sarah/sarah_michelle_gellar_62.jpg 

It's not exactly the same. But Allison has similar upper ridges to Sarah, although they are not as pronounced. What do you think? What kind of nose would you call it? I think it's of Welsh origin.

Do you know anyone that has some similarities to a Buffy/Angel character as well that I could see? :D
