For the most part you did not answer the question , as that bit metioning her personality I recon that your right , however Im talking about the outside appearance.
Did'nt you notice how these 10's usually look more specifically intergtrationally designed in visual beauty than lower standards ( 9s or 8s), thus its more challenging to neg them on looks basis.
E.g. you want to neg model/actress Keira Knightly , what would you actually say 
"Hi skinny!", how about that for example?
I can`t belive that you lack of imagination so much. You can always find something that, even though it looks perfect for you, someone else finds it not as nearly as perfect as you do.
NOBODY IS PERFECT! Not any human being on our planet. Everybody has something they would change on itself.
But even if some girl looks flawless to you, how about this neg for "perfect babes": "You are pretty cute, but I wonder how do you look WITHOUT all that makeup?" (Btw, have you ever seen those pictures of celebrities without makeup and Photoshop? Search a bit on the net)
Or even, more bold and direct: "Yep, you look nice in the club, but I am a bit affraid would I be dissapointed if I saw you early in the morning in my bed without all that makeup?"
Did I now answer you more directly?
