She has great eyes, don't get me wrong, but they're just HUGE! :o Really big! xD I'd make them smaller, and maybe give a little bigger nose.

If I had to change anything, I would make her and Honeymaren's friendship (and possible romance) a bigger part of the story.

Never fix what isn't broken :)

If hypothetically I were her character designer, I might have gone in a different direction. The main thing I can think of is I would have explored her socially awkward side more. It's an area of her personality that I really love seeing and continue to be more interested in (especially as it's probably the thing about her I can relate to the most). I wouldn't change her personality as such though, just maybe pay more attention to that particular area of it.

Something I know I would not change about her (and I know some will disagree, although no one's voted for it yet!) is her voice. I feel like Idina Menzel's voice is an acquired taste, as it is very unique and she certainly has her own sound. I had the advantage of being addicted to the Wicked Original Broadway cast soundtrack (I actually saw Wicked the same year Frozen was released - not with Idina in it of course, but that's how I started listening to the soundtrack). But I do know that her voice is not everyone's cup of tea, so I do get it when some people say it's not for them. But personally I love her voice. :)

I'd make her not worry about her powers so much and learn to control them better that's the only thing I'd change about her
