Doing a realistic female portrait is always something that is on the top of my to-do list. Here is a WIP of the portrait converted into BW using Lightroom. Modeled & Textured in Zbrush , Hairs are fibremeshes converted into guide curves for Maya nHair . Rendering was done in Arnold. Which is really fast even working with hi polygon meshes. Since I have no plans for animation I didn't use displacement and Arnold render it fast and efficient.
