I was part of the team that modeled the robotic pieces of Nicki. Paulette Harutnian modeled the face, Mario Quan modeled the arms and Kris Fancsali modeled the legs. I modeled the spine, ribcage and mechanical innards of the torso and neck. Lookdev was done initially by Jon Balcome and the lighting and additional lookdev was done by Scott Metzger.

Here are some beauty renders, courtesy of COPA. When I get a better handle on V-Ray I'll do some renders that better showcase my contribution. For now, enjoy!
As promised, here's a better view of the torso. I left the head because Paulette and I overlapped a little bit working on the neck. Also it looks bizarre enough without arms and legs.
