Shiva model!

[KaMuiSouZou]

The coloring you see on the zbrush model has absolutely nothing to do with final in-game colors. This entire model will later get converted into a polygonal model, which will then get textured and colored. The current colors of Shiva are placeholders to tell modelers what's what. They could've picked any color to differentiate the features (ZBrush models are also often only one color).

You can see the process using XIV's Morbol and Ifrit here from "The Making of a Realm" series wayyy back at release time. The current Shiva models are the equivalent to the all-red models in this video.

Compare the concept art of released primals to their final in-game versions to Shiva's concept art and you'll get an idea of what she'll look like in the end. They are very faithful color wise to the concepts.

The only opinion I would really say is I think her face lost something in the modeling. In the concept art, she has a much rounder face with a larger forehead (plus what appears to be a gem that is missing) that gives her a demure, mysterious ice queen look. The angry expression and low, angled forehead loses her regalness that is more fitting for Garuda or say Siren. It also does remind you of an Elezen, which I think is unintentional and not what they are going for.
