The only thing I don't like about her are the "ears" on her shawl. They stand out so much from the outfit, and it is not a good thing when the first and biggest thing that stands out to me when I look at her is not the nice color combination of white and red, or the way that her dress is infused with Ishiwatari's signature metalic and belt infused style, but rather these silly long protuberances on her head.
Anyway... it just struck me that GG has never really had a "girly" character before. I mean, we have May and Jam, but the former is more tomboyish than anything, and Jam strikes me more as ditzy and energetic rather than a frilly Genki girl. If there is something to praise the series for, it is that there really isn't any overlap when it comes to character aesthetics, base concept, and purpose. Granted I'm assuming what she'll be based on appearance and her VA, but it is an interesting detail to note.
