Jabberwocky - you are one sick miniature painter - welcome to the club! lol I am thinking of the been-in the ground-awhile look. There are no patches to the cloak, but there are all these skulls on it, so I\'m not sure I would be able to do much to create any seams on it. But now that I think about it, a robe would have to be made up of smaller pieces of skin, so I will have to try it.
Supervike - maybe Reaper Oiled Leather, highlighted with a fleshtone? I like the idea of the green wash too, I will have to try that as a test first and use it if it looks right.
These old Heartbreaker figures always get my imagination going because they are so over the top.
