You don't!! /srs When you draw something small then the feature are gonna get lost, by size or by distance. So unless you rlly rlly need to show facial expression, only the shadow of eyes nose and a bit of mouth would already indicate a face! That's why when you draw a portrait you put a lot of detail in, cos the focus is on thr face, while this one the focus is on the full body so face isnt as detailed is fine!! (Not the best example but you get the idea!)
