This is a personal project I started a long time ago and I very recently finished.
Each one of them was done in more or less one hour so they are pretty rough and have no details.
Bare in mind than these portraits are my own personal take on the characters from pre-heresy times and they are not official.
I also did a series on my Youtube channel showing the process of each one of them. If you scroll down you will see a link to one of the video ;)
