i like the bottom pic more.. that one actually looks like shiva
Dito. The one that isn't fat and tanned.
She isn't fat - she has thick, muscular thighs, like an American super heroine, or an action game fighter like Chun Li. I think that's rather neat.
I can picture the conversation now...
Xoie: Wow! What a detailed ice sculpture of Rinsui!
Catwho: That is Rinsui.
Xoie: It is? What happened to him?
Catwho: He called Shiva fat.
Xoie: Oooooh. That explains it then.
Kidding aside, the concept art is a bit more stylized than completely practical. Shiva's thighs and hips flare out a great deal, her chest is proudly stuck out with almost an impossible posture, her arms are bigger and her head is smaller, and her hair is spiked up like a crown. It creates the illusion of a tall, regal warrior through the trickery of perspective, but that's exactly the inspiration that concept art is supposed to invoke.
Her 3D model is a bit more human in proportion and a little less conceptual. But I'm sure they'll make more adjustments that draws more upon the original source of inspiration. It's a work in progress.
