How to paint Endless Spells Part 1 (Bone Tithe Shrieker)

Hello everyone, I hope everyone is doing great and being healthy.
Here is the First part of the Ossiarch Bonereapers Endless Spells painting tutorial video.
In this video I am focusing on the Bone Tithe Shrieker. It is a four-headed, all seeing monstrosity conjured to hunt down those who would escape the Ossiarch Tithe. I have decided to separate them in a playlist: this is because I am trying to show how I painted a three-miniature unit in three different, shorter videos, so that you can focus better on each piece individually. As mentioned in the video here is the link for the basing if you are interested:
