In my opinion, the skirt is way too flat, it's just blah, and the sleeves are eck. I understand that they are styled after her wedding dress in the end, but they're just too much. The bodice is nice, and the coloring isn't that bad, I also don't like that they took away the hair piece.
This is the worst of the redesigns IMO, it looks nothing like Ariel at all, and it just looks like a cheap costume. I've seen fan made cosplays that look a world of better than this, and it was based off the same dress in the merchandise. I find the other redesigns to be great, but not this one...
