It's a lot more Cartoony than Parrilo's visualizations of Sonja, but I like this 3D-rendered Sonja. Here's what the artist had to say about it:
For a change I decided to work to a concept so I chose one by artist Dominic Marco which was not only cool, but also matched my own style.
I built her in Silo before rendering in Maya. I then tweaked her and added further details in Photoshop.
And if you prefer Parrillo, there's a Parrillo gallery containing Sonja stuff there, too.
