I don't post on polycount often, but I should!
For the past few months I have been taking a course with CGMA called characters for Films and Cinematics with Pete Zoppi and I could not recommend this course more. It is an amazing course and Pete was really helpful with everything.
Hair was done in XGEN and all renders in Arnold.
Skin and displacement were done with mudbox and zbrush with the help of Texturing XYZ assets.
All the hard surface modelling done in Maya.
Clothes were first drafted in marvelous designer, then maya for retopo. Then after sculpted with zbrush.
