I found it really difficult to do facial tattoos on the Empress minis as the facial details were very fine and sharp with limited flat spaces....I did around 3-5 with facial tattoos but felt it took away from the overall look of the mini and did not look as realistic as I wanted....also I was attemping to layer them with 3 levels of colour. It was extremely difficult to replicate the complexity of the tattoos on such a small area to work with.
Below is an example of one of the better ones.
