Face-Claim much?

So. I'm having trouble choosing a face claim for a charry I'm working on. Shes a vixen, a girl who gets jealous easily, loves swimming and could be compared to a flighty, possessive mermaid. Vain, selfish, pretty, but with a curious, open side too.

With all that said, who do you think is best?

Blake Lively--the beach babe, blonde and beautiful with tan skin she belongs in a bathing suit on the beach at all times:

Nina Dobrev-she has a wilder look and is brunette. Fits the vixen part, but her thoughtful look might not work. Heck, shes still pretty and I love her so shes up...

Edie Campbell-Shes blond with deep blue eyes that I could describe as being mischievous and curious. I love the turquoise in her hair when she models for Marc Jacobs, so because of her owning hair I put her up...
