Heather's head is nestled in her hand, not in a defensive attitude, but in a relaxed and interested way.

Her lips curl into a smile and while she is absorbed in the TV ad she absent-mindedly strokes her mouth with her little finger.

At the moment of seeing an amusing scene, she exhales air and her shoulders shake.

Her eyes widen with pleasure.

The smile stays on her mouth in a natural way as she appreciates the video.

Her eyes actively search out the action in the ad (of a football celebration in Africa).
