This is an image of the silhouette and shadow of a woman. The shot is taken at night and the woman is walking in a street alone.

This shot is a good representation of thriller because of its enigmatic elements, where you cannot see the character. This makes her look vulnerable as she is walking alone in the centre of the image, with the shadow she is casting dominating the image.

The light source is coming from behind the character and reflecting off of the ground, possibly signifying that there is something chasing her.
