I voted for Jenascia, because she doesn't seem to rising to the challenge at all, and I don't like her vaguely porcine mouth/nose look. She always looks overwhelmed and pugnacious to me. On the other hand, Heather isn't doing too much either, and--as omeone pointed out-- she has a very generic look.
I want to see Sarah do something more striking. She is gorgeous, but not individual enough so far. Mercedes is a cutie, and building her own litte niche (great job on the shoe thing). Camille is a monster of ego, but unfortunately she is also good. Xiomarra will have to transform to make it to the end, but I can't see them cutting her yet. Same thing with Shandi. Catie is okay, and besides, how could they cut the poor girl immediately after chopping off all her hair! No way will April go--she's the best so far.
