I think she looks awesome. Not in a way most people mean it, but athletically. I agree she doesn't look too skinny to me. Look at Novak, he's also skinny, in the sense he almost has no fat only muscles. I want Ana to be like that too.
Actually not really, I just want her to win GS titles, and as far as I am concerned she can look like Kleybanova or Serena if she can achieve it.
