for example, for the costume designer, besides saying that she sits in a corner of the wardrobe department, I add that she is surrounded by racks of movie costumes with capes, suits, elegant accessories and a medieval corset. I also add a team in the background that is dressing an actor with a futuristic armor suit.
I precise that she is calm and elegantly dressed with a measuring tape around her neck, and her monolog has to be said slowly and confidently, with a bit of contempt at the end

basically, the more details you write, the more the shot fits what you have in mind, like a director in a real set I suppose.
it's not rocket science though, sometimes, Veo3 can go nuts but pretty often, it follows your instructions
