Okay, so I only had a few hours that I have been able to work on this so I was only able to put together my rough forms of things. I should have some time soon to really dig my teeth into it though. Anyway, I like to give my characters a backstory and think about who the person is and how that would reflect the way they look, even though it sounds silly to sit and write down notes about your own fictional character ahaha. The jist of it is that he has been cursed with "immortality", and has been walking the earth for many years.
My plan is to have lots of articles of clothing, but at the same time I dont want to bury him in it, and I still want a good chunk of his skeletal body to be seen as thats the main point of the character. I plan on opening up his chest cavity to help with this. The images below are very rough and are subject to change a lot from various ideas I have later.
