Story in flat images

Some images contain an entire story. While it is hard to match the effect of this photo in an everyday presentation, you should at least try to use cinematic effects in composition: suggest movement, create tension of something that is about to happen, but has not yet. The man who is about to open the door creates a much stronger visual, than the image 5 seconds later of him escaping the women's dressing room.
