I’ve only read one of Stephen King’s books, the anthology with The Mist in it. It’s fairly good. He’s a very distinctive looking man. When you go to draw him the thing that stands out is that gap between bottom of his nose and top lip.
Also his nose reminds me of that thing you might have in the kitchen to hang up tea towels. Where you stick the corner of them into the little holes? He could hang two tea-towels on himself and go to a fancy dress party.
