I personally still think it's far too close to the comic version to be fit into the film's world visually. I'd planned on coming up with my own interpretation, and one of the things that I constantly got stuck on thinking about the design was Death's portcullis helmet. The idea of him bashing in strips of metal with nails like this concept was something I thought of too, and of course the rest of his attire: the bird on his shoulder, and the bones for the other pad as well as the skull-shaped badge. It's hard to imagine having those there with any realistic context as to why they'd be there. Remember, the film version is a realistic, gritty and plausible world. I'd personally just imagine Death to be a badly mutilated judge that is somewhat decayed with protruding teeth, creepy as fuck, and wearing a regular uniform with maybe a cracked visor where you can glimps a supernaturally lit white glowing eye.
