How to Pose Your Face
The Eyes
The trick to the squinch is to squint slightly, but mostly with your lower eyelids. Your top eyelids will come down a little, but not so much you’ll look like you’re squinting and need glasses.
The Mouth
The first step to posing your mouth is to not do anything else with it. That means no talking, no big say-cheese photo grins, and no over-the-top pouting.
To give the appearance of a natural and flattering smile lightly press your lips together, then pull the edges of your mouth up into a half-smile.
The Jaw
To get a strong photo-jawline, you need to exaggerate it by extending your neck and leaning your head slightly forward, pointing the tip of your nose at the camera—a bit like the chestburster in Alien.
