I thought Kirstie Alley looked great, especially during the turbolift scene when she was out of her duty uniform and her hair was down.
As for Jolene, that pic above is one of the best I've ever seen of her. She looks more natural and not plastic and emaciated which is what she looks like in most of her pics. And about the long hair on T'Pol, I speculated early on in the series that they'd let it get longer toward the end and that she'd have a more human disposition. Unfortunately the show got cancelled before that happened, but it was going in that direction wasn't it?
