I've been thinking for a long time about making this portrait. This is my first character with a hint of photorealism, but I have another character that is also in progress, so stay tuned!
I've spent a lot of time on Tyrion's hair, which took a lot of tests and tunings. Several times, I returned to tweak the hair during the work process. Moreover, there were some troubles with the material. But now I seem to have worked out all the things, so it will be easier with the next character.
Modeling, render (cycles), compositing was all done in Blender. Sculpting and texturing were in Zbrush.
