She's very pretty but I have to agree with drkim: Tonight's solo was the best dance she's done all season.
Since she didn't even dance fabulous with Benji (and Benji appears to be gold for the girls) I can't see her going much further. In fact, I thought she should have been out tonight and Allison should have stayed.
I have this feeling that Natalie needs to be the star in any routine she does so she overpowers her partners. Technically, her dance moves are fine -- where the overpowering comes in is with her head movements. When she should be dancing off into the background, she continues to shake her head like "Look at me!" and I find it really distracting. One of Donyelle's best attributes is that she knows how to use her head to say "Look at my partner!"
I think she could really use some classes in partner dances to become a really strong competitor. Otherwise, she's a really pretty girl who can dance. I just don't see her going much further.
