I don't care for the Emma Watson head. Like many celebrity dolls, it's not very attractive, but it's not as bad as some have been. I think the clothes should also be a lot better, considering the retail prices. The ballroom pair are $50, the prince set is $40, the singing doll is $30, the basic ballgown Belle is $20, and the peasant Belle is $15.
I do like the prince. I think he's got a nice generic face, and could be redressed in something better. His hair is molded on, but I don't mind so much, 18th century heads are a rarity. I'd like to get one if they go on clearance.
The rest of the photos. I believe each Belle head has a slightly different paint color selection. The singing doll has pinker blush, and a mole.
