Short Lighting
When a subject turns their head, light the side less exposed to the camera and let the larger, nearer side fall into shadow.
Prompt
Use Short Lighting on the existing turned head: illuminate the smaller far cheek plane on image-right of the nose, facing the direction of the original gaze, with a key from camera-right. Keep the larger near cheek plane on image-left substantially darker but readable. Keep the original head rotation, gaze and facial anatomy exactly; do not rotate the head. Carry the same source direction into the existing clothing and notebook, with subdued ambient fill.

Effect comparison
In the baseline image, KaiMiren holds a turned head position with relatively even facial lighting. Short lighting illuminates the narrow, farther side of the face and the side of the nose in the direction of the gaze, leaving the broader, camera-facing cheek in shadow. Confining the bright area to the narrower side emphasizes the face's turn and the extent of its shadows.
