Macabre or partly dead couple.

How about a macabre couple. Like as if they are slowly rotting where you can see their flesh on one side and part of their skeleton is showing on the other side or something to that effect. The couple will be holding onto each other perhaps embracing in a form where they are standing. The female resting against the male and his arms wrapped around her. Or some type of holding/cuddling pose. Clothing like a gothic style.
