I was responsible for creating the heads of the Lead Actress in the Mumbai level. The head was based on concept art and was done in ZBrush by adding features on layers in order to iterate non-destructively. Details are added by using a combination of sculpting, scan and XYZ maps. The skin is generated and further worked on in Substance Painter.
The model is real-time rendered in-game and the highpoly pictures are captured from ZBrush. The haircut was made by me and fitted to match all female heads; consisting of around 10k tris each. It's hand-placed in Maya with the help of plugin scripts and based on both photographic references and concept art.
