These may not be what you expected, but I hope that they'd roll live up to your expectations. I had to look around for awhile to find images that would work, and found a couple. I incorporated some of the things you said represented King, and I hope that you like it RowanCarver !

So I found a super cool image of a cyberpunk version of the Grim Reaper and had to make cover from it, even though it doesn't really fit the book...
