Being a huge Disney nerd I have to nitpick: Ariel is wearing the wrong dress in the Magical Kiss set. Given it represents the "Kiss the Girl" moment in the movie she's supposed to be wearing a blue dress with a black bodice. The pink gown appears in the dinner scene when she combs her hair with a fork.
Anyway, these sets look appealing and I like Rapunzel's Tower and Ariel's Amazing Treasure (Flounder!) most out of the bunch and will most likely pick up the mermaid one.
