Ariel, Tiana, Mulan, Pocahontas, Jasmine Snow White and Rapunzel don't look that much different.
Aurora's is looks simular, but different.
Belle..I would prefer for her hair to be smooth, instead of having broken strands of hair on her head.
Cinderella looks a tad Justin Beiberish
I am not sure if they wanted to make the hair look more realistic...
