Motion blur on everything except the subject is what makes a still read as a moment. It also softens exactly the areas where a rendered street falls apart.
The recipe
The shot never describes the person. It describes what is happening to them, which is what keeps the face out of the variables.
Getting it right
Composed
The locked line comes from the character sheet; everything after it comes from the recipe above. Swap in your own line and nothing else changes.
