Another attempt to do photorealistic portraits of the main characters from The Witcher 3, by CD Projekt Red.

Ciri based on: https://www.deviantart.com/walter-nest/art/Ciri-HD-Head-Render-777012406
(I didn't have to much with that one.)
Triss based on: http://tiny.cc/c9io4y
Geralt and Yen are based on screenshots whose authors's names I don't know.
