I do like the choice of fabrics and prints used on their skirts. I guess the school has a very loosely defined bodice-and-skirt dress code/uniform?
I hated their boots/legwarmers in the artwork, and don't like them much more in plastic form - I was theorizing they might help the dolls stand on their own, but I'm not so sure about that now. And why is Applejack wearing a cloche?
As for the dolls themselves, I prefer the closed mouth heads, something looks a little off about the ones with teeth.
Way too much eye makeup, but then all their lipstick is generic red or pink? At least give Rarity a nice plum, she isn't wearing a speck of pink!
Those tails need to go, they didn't even curl Pinkie Pie's.
Despite my nitpicking, they could be more terrible. But... well, but. It might be nice to see one in the hands of a customizer who's good at new face ups and making shoes, to start.
Seriously, my least favorite part has always been the shoes.
