I like Merida's redesign better. She looks a little order, more feminine, and more attractive. Like she would if she was a little older. Mulan's is okay but I don't think it does her justice.
Mulan could be in my top 5 with this design which makes her's better, Merida looks barely like herself and it's just a glamorized version which I'll admit is better than the original but seeing as she was against this sort of thing makes me laugh.
Merida. She looks older, her eyes have eyelids, and her neck isn't as huge. Also her head is usually super round but now it's quite beautiful. He dress is better because they did not over glitter it, and she has the most gold. Gold look best with sparkles in this case. Mulan's face is completely different and her dress makes her chest too firm.
