You're killing me. There was nothing amateur about this woman. This is professional BB, not professional dance. She's an awesome performer!
Let's try the 1986 Ms. O routine. Check out the shades during the interview. 
I figured out what was "off" about the Grease routine. She is prancing around like a playful dumbe blonde might do. Now that might work if she were just a little thing, but she is too muscular for that type of dance imo. I am not saying she looks masculine(I mean she does a little obviously), she is actually quite attractive. But that whole routine has cutesy written all over it and she is too muscular for it to work for me. Just my honest opinion.
