The figure is centered in the frame with a light source eminating from a source coming from the left. The shot is well lit with a little drop off over the shoulder of the figure. The image is desaturated. The darkest parts of her seem to match the blackness of the background.
Depending on what you see the woman is either A) young and looking back and to the left or B) elderly and looking directly left of frame.
Not being able to see the young woman's face makes her a little mysterious because you can't tell read her facial emotions. The fact that she is facing away from you could indicate that she doesn't want to look at you, perhaps disgusted. She could also be gazing or daydreaming and not paying attention.
The elderly woman seems to have a certain sadness about her. Her eyes give me that impression. However, her mouth seems to be smiling. Either she's hiding her sadness with a smile or she's so happy that she's moved to tears.
I chose this image because it first tests you on which age you see first, but also because it is a visual depiction of how we all will be both young and old in our lifetimes.
