All too often characters are described as though the author is writing for a police blotter: hair, height, eye color. If the character is female there's usually something about her desirability factor.
This kind of flat description does not bode well for an imaginative twisty zesty manuscript.
So, what am I looking for instead?
Here's a good example, from City of Windows by Robert Pobi (Minotaur: forthcoming August 2019) Lucas is the POV main character; he's in Wyoming meeting the local law:
Sheriff Brice "Bronco" Doyle was a tall man a few years into his fifties, with a solid set of shoulders and a head that could have been hammered out of a paint bucket. ...He had a cross pin on his lapel beside the American flag, and he carried a pair of pistols in a tooled old-time holster that had the mirror image of Jesus worked into the pockets. Doyle gave the impression that he was the kind of man you'd want at your side when you ran out of ammunition and the cannibals made it over the fence. But there was nothing humorous about his disposition and he didn't smile much. But what weirded Lucas out was that for a small-town sheriff on the edge of civilization, he had yet to swear.
After reading this, you have a three-dimensional view of Sheriff Doyle, not a police blotter sketch.
This is the type of description that makes me shiver with delight and anticipation when I'm reading a requested full.
