I wouldn't go as far to call Anna a icon, cause she is not yet. I guess the mix between Lara and Claudia makes her for me interesting. I do think they make her sometimes look or reminds me to much of Lara (last vp cover) or Claudia. However when she is just her i see that mix with the Bardot in her.
Anna is a great printmodel, really versatile. She is young, but sexy in a mature way. She doesn't have to try to be, she is sexy unlike her besties Lexi and Binx (who I both find boring).
I also think she has a great personallity. This may sound weird but I notice that topmodels like Lara and Natasha (photo together on instagram) follow her. Well Natasha follows tons of models, Lara not. Lara worked with Molly for example for VI and W but does not follow her or Binx or Daphne.
