That's going to take a lot of pots of miniature paint to get done right!
Perhaps a basecoating of Abaddon black, followed by a mixture of Averland Sunset - highlighted up with Balthasar Gold - and some inking with Mournfang Brown. It may take a few decades and several million dollars when using those tiny paint pots, but the end result will be....mediocre.
Wrong forum perhaps

But thanks for stopping by.
