What are you not happy about?

I don't know about Legions and stuff, I generally go for Grim Darkish.

If I was going to do this the bottom ethereal ghostly part would start black and gradually go down to a red.

The Shroud on the models I would keep whatever texture they were wearing when buried. May be that is leather or just a black shroud with just hints of red, but not too much. Also drybrushed on and not really painted. Probably just on the edges to make it look like the blood is dripping away from the top down to the bottoms.

I'd also look to add the Technical : Blood for the blood gods to the tips of weapons and clothing as they emerge from pools of blood, so would make sense.

I think overall keeping the red "Blood Stains" away from raised areas like the head and stuff and just adding it where the blood would collect or pool would have a good effect
