Thank you all so much for your kind feedback!
@Blend Master I'm seriously considering buying a good mic so I can make some tutorials for you guys It's the least I could do for the community that's given me so much.
In the meantime, text will have to suffice. For anyone who is interested, here is a link to a "Making of" that I wrote for the CG site treddi.com (I believe it can be viewed in English and Italian) https://www.treddi.com/en/cms/making...portrait/3044/ This is a fairly brief overview, but it does show some detailed screenshots particularly of my Skin shader setup, hair setup, and lighting. I hope you find something of interest...
@mrford3rd: See the above link for some info on how I approached the hair
