So I am almost finished painting my night lords raptor units and want to represent them as members of the bleeding eyes cult from the night lords omnibus. However it seems as though they don't really have any definitive markings, I was thinking of using blood for the blood god to make there eye lenses actually bleeding but I don't think that is how they adopted that title. I was flipping through the book looking for some ideas but have not come across anything yet. Any advice would be welcome.
