Corner Cover

A cover (or other high profile still image) that features a character taking cover with their back to a wall next to a corner while the audience sees around the corner. This simultaneously allows a frontal shot of the hero, gives the image depth, displays of some manner of antagonist, and conveys a sense of danger.
