I thought that for this episode, Christian was the clear winner. Not my taste, really, but clearly he had a vision, was inspired by his art, and really well made.
I suspect he will win the whole shebang, because of his high-fashion collection. My personal favorite collection was Jillian's -- I thought her jackets were amazing. I also liked a good deal of Rami's stuff. I wasn't big on either Chris' or Sweet P's (though whether I liked her collection is moot at this point, since we know she was a decoy). As Tim would say, chacun a son goute.
For the 3d Spot Design-off between Rami and Chris, I would go with:
For Chris: 1) the first piece (blue with face); 2) the eighth piece (red and black worn by Dani(elle) from ANTM; 3) the twelfth piece black with shawl/collar worn by Marcia.
For Rami: 1) the third piece (black and grey -- stunning without the jacket; I think he should have ditched that jacket with the dress entirely); 2) the ninth piece (olive/gold woven bodice worn my Amanda from Season 3); 3) the eleventh or twelfth piece (gold and cream ribbons/black ribbons -- both are stunning and probably his top two pieces, but I think showing the judges two similar pieces, even if not draped, would have ticked the judges off!!).
Overall, based on those looks, I would give Rami the third spot by a landslide, but as I said earlier, that is just my opinion.
I don't think Posh is a great judge for the finale. I am not really big on the celebrity judges for the finale at all, because they choose celebrities who aren't even noted for being fashion icons. Posh maybe, but not in a good way (see, e.g., her inclusion on Mr. Blackwell's Worst-Dressed List). I'd rather see people like SJP who are at least noted for their fashion choices (understand why they didn't use her this year), or noted designers or other people related to fashion (journalists, like Fern Malis, for example).
