Alyona: Her features are kinda big and unwieldy for her face, but she's still interestingly cute.
 
Anne: The most interesting one out of the pack. Reminds me of a much prettier Michele Hicks (sp).
 
Bette: A deadringer for Polina K in her b/w headshot (which is promising), but unfortunately does not fare as well in her other snaps. 
 
Eva: Really pretty, but rather unexciting.
 
Nora: A watered-down version of Sydonie Herrera. Unusually attractive, but not a true "find".
 
Rhaisa: A more "conventional-looking" Raquel Zimmermann. Meh.
 
Selena: Attractive, but but that's the extent of it.
 
Bottom line: Eva is the "prettiest", but Anne has the most potential as a model, imo.
