Sorry, it's just that it really sounded like all you cared is some "visual references" to draw off, and make them do whatever's useful for you in the scene.
What I mean is that for example while Kenku would be a good shopkeeper (or quite possibly a pirate-musketeer
), he probably wouldn't like to be drawn, even in the background, as the royal executioner with a huge axe.
If someone is an armorer, you probably could draw him as that, or as a basic smith he probably was before specializing - but he'd probably wouldn't "feel right" drawn as a mage.
And of course, nearly anyone, except maybe assassins, can be drawn as "just a random pedestrian".
So as long as you'll listen to the short basic "(s)he's that and this and would never that" one-two sentence description people would sure post along the ref and honor that when choosing as to what place and occupation to draw this particular background stunt-fuzzie in, all sides should be happy.
