I am sad to say that c914 has not been in contact for some time, and many PM's have gone unanswered. A while ago he stated that in two weeks he would be able to show me some progress, but I have not heard from him since then and it has been well over two weeks.
That being said, I went ahead and gave it a go myself. Be nice, this is my first texture job!

Planned: Obviously finish it... and darken it. All of the red will be in the glow map.
FAQ (from those that have seen it):
Q: What's with the yellow bits?
A: This is a direct note from the book of c914. His Cain actually features this yellow/gold a fair amount. It keeps the somewhat desaturated doomish look while adding subtly changes. I may have over done it a bit though.
Q: When is it going to be done?
A: I have no idea. Soon? Hopefully before March.
Q: Why have you not added any red?
A: This will be in the Glow map.
Q: Will you use any tiling?
A: No.
