I personally really like it. I think the hair looks a little more natural, with still being princess perfect, the bun's no longer on the very top of her head. I do wish they'd kept the curls a little more relaxed though!
In terms of the dress, I like it, it took some getting used to, and looking at a lot of different pictures from different angles to really start liking it. Same with Cindy, I didn't like it at first. However I think the dress looks more "golden" rather than "crayon yellow" and it looks like it flows more. I've always thought Belle's dress was too stiff in the parks, it doesn't move or flow like it does in the movie. I've seen pics of other princesses in overseas parks with just lots of crinoline under their skirts to make them big poofy but also move well, an I wish they'd do that instead of the big hoops, but aside from that, I really like it!
I briefly saw some people asking about other redesigns, and from what I've heard, Aurora, Ariel and Snow are getting make overs in the parks, while the others aren't. I haven't even seen anything with Merida in it on the merchandise, and personally, if they made her sparkaly, that's just not right. I also don't think they need to redo Ariel in the parks, I love that dress
