Bastila reminds me of a porcelain doll with her deathly pale skin and large head with childlike features. Mira has flat, dead eyes and looks perpetually pissed off. Juhani is a bit too alien for my tastes. The Handmaiden's features remind me of some greek amazon depiction for some reason.
I wouldn't say any of them are really "hot", if I had to pick one it would probably be Visas (if you disregard that there is an empty void inside her mouth) since what little you see of her makes her look a bit exotic and mysterious.
