You're probably right. My feeling the Vannilla sprite are less detailled is cause they have that "big thick brush" aspect. Anyway we'll probably see amazing things in 2D next gen!
And even in 3D. When you think about it, the original Shinkiro style is now totally doable really faithfully in 3D.
I was surprised when I saw how "Big brush" Ogura's coloring looked up close; his addition of black linework for the outlines certain details really meshes very well, and makes the images look very sharp. There's nothing to draw that kind of visual-trickery contras in Kamitani's, but that might even work better for a crazy beat'em-up, as it helps things look kind of raw and vicious; and if it's all TOO sharp, we might hear many of the complains that people levy aganist Skullgirls, with too much of the action blending together.
I'd truly love to see people work modern 3D in more artistic ways; it's the one thing I really love about Capcom's 3D fighters (and even other 3D work like MonHun), they really try to capture 2D dynamics within their modeling and animation, to varying degrees.
Oh, and just off hand, even though vector animation isn't my fav, I have to give it to Vanilaware for the details they DO get in there; Watching just this trailer, and noticing little details such as how the fire before the wizard actually gleams in his eyes, is pretty nice.
Who designed these characters? Why? Their absurd proportions look calculated to titillate rather than communicate anything in-fiction about the world. This really frustrates me. Don't make me embarrassed to play your games.
The Amazon has nice huge hips, sure, but she's also a very obviously muscular woman, which makes one think more about a body-builder, rather than a super model. In context of the full game, I find the Sorceress much more ridiculous, because everything about her seem to be about the breast; it's a focal point of bascally all her animations.
And it communicates loads about the "in-fiction" about the world; none of the non-amazing charactrs seen in that trailer are as exaggerated as ANY of the main characters, males included. The status look like "normal" people; the Skeletons look normal, the non-combatants all look pretty normal; it's only Player Characters and Impressive enemies that look exaggerated.
This is a defining idea of Beat'em Ups; your characters generally are always more dynamic and crazy than noraml background characters, or even the "cannon fodder" enemies. Wheither it is by art style, animation, proportions, or coloration, this is a standard feature of the genre. The bosses are then a step beyond THAT, to make them imposing.
And at least, generally speaking, these are exaggerated adult characters. At least we're not looking at a group of obviously under-aged girls fighting in sailor outfits, where every animation ends with some sexually-themed camera angle, and clothing is purposely destroyed in suggestive ways on the female cast. And there's also nothing incredibly sexual going on in the gameplay, or even cinematics, from what we've seen so far. It all seems to begin and end at the initial designs, and it actually seems much more evenly dispersed than it could be.
