Offline renderer do work different. You wont need all those maps. If you use an AO for example you just get much to dark areas. Your render will look less real. If you are aiming for a stylised look i would mix in AO with a layered texture node. Take a look at Arvids tutorials. https://youtu.be/aN4sqlfbTBA
Make a heightmap and make a normalmap out of that with for example crazybump. Or turn it into geometry using a displacement map and bake it however you want.
well but vampires have been in folklore since... well.. ever, and before the 19th century or something they were not represented as they are in Dracula for example.
