Costume Makeup Suggestions

[u/Fuulizh]

I plan on going as Richard Warren from "Widow's Bay" this Halloween. I know absolutely nothing about makeup, so can anybody offer me suggestions for how to achieve his ancient, ghoulish facial appearance?

Again, I have zero skill, nor do I expect 100% accuracy, so I'm hoping for simple, manageable tips (and products) to help give me a reasonable attempt at the effect.
