A timeless Claudia.
Last month I worked on a likeness. I took several references from the actress Claudia Black, younger and older. At the end I stayed with the ones with more resolution, so the result is based on those. I made the main skin color using Zbrush vertex paint and I almost didn't open substance painter after the baking, As I preferred photoshop this time because I just worked on the skin and I found it more quick so I could check the textures with Toolbag.
For the hair I used the Addon for Blender from https://gumroad.com/l/hairtool, adapting it to my own hair textures. I recommend it a lot if your workflow is based on designing the hair using curve tubes as I do.
