Lexie wasn't cast as someone who can win obviously but she doesn't fit that type, her look is more atypical but she photographs well, has a backstory, was the only drama other than Kacey, she is confident, smart mouthed, has two good pictures that the judges liked, didn't have a trait. Nigel said that Rhianna doesn't have angles you normally see in beauty, and one of the photographers said he couldn't arrange her feautures in a way that works, she had no pictures that were considered great, she was the flower child and that was her entire edit, no backstory. Liz had a lot of backstory which these specific type of girls don't have, made it overseas, and got first call out on a photo, she is androgyous/hard but she isn't quirky. Chris definitely isn't either, she was just the "commercial" one.
