I literally hate every single design of Wil. The only Zola design I truly like is Kyo's Carnelian one because it reminds me of Kamijo from Versailles and he looks cool, fashionable, and intimidating. I don't like how all of the designs for Yuu are really girly and strange (the Carnelian one and Amano one are okayish in terms of color and being the most "solid" character impression compared to most of Kyo/Wil's designs), but why can't Yuu be short, like pink, but also not look like Honey-senpai? orz
I feel like having the sketchy box art is kind of lame, because even for his sketchy art style for Final Fantasy logos, the composition is always amazing, artistic, delicate. But for the Zolas, it looks SO phoned in, Yuu and Wil don't even have shoes (just pants that turn into shoes), a really cool (sarcasm) white background to inspire you to create, really awesome T-shirts and mullets--whoo boy! Nothing screams futuristic software than Dr. Seuss pants and "I'm on my day off" T-shirts by the most iconic RPG artist! I feel like you can't even display the box art if you own it because it's just them standing around uninterestingly. I bet if someone who didn't know much about vocal synths saw their box and you said they were voice banks, they'd probably be like, "Er.... okay???"
The other designs to chose from range from Super Saiyan with tall hair, to budget Walmart bin BL comic main characters, to "How to Draw Manga" bizarre hodge-podge vaguely fantasy clothing. Gosh, typing this literally made my blood pressure go up.
As someone who likes to design alternate outfits for Vocaloids, they are stinking hard to work with. It is SO hard trying to match their really weird color schemes as a unit. They should have all had a limited set of colors (ex: Black, aqua, gold) and not... Wil = aqua, red, greyish brown, grey, black / Yuu = pink, aqua, gold, purpleish grey / Kyo = blue, black, gold (something like that). Somehow when compared to Cryptonloids and VSingers or any duo like Lapis/Merli, they just seem so random, like every designer was very confused.
Sorry for ranting so much. I am, er... passionate about Zola Project. Thank you for coming to my TED talk.
