3D modeling Zbrush, face detail, realism

I have studied several master classes related to what you require. I can provide detailed sample renders with realistic skin rendering as well. The final topology of the mesh will be highly suitable for animation / facial rigging. I can also offer services for realistic facial rigging et al. afterwards if needed. I mainly use Maya, 3ds Max, Rhino, ZBrush, and use various others tools here and there as needed.
