I'm not voting on this one because I don't want to give a really low score. This is not a Still Life. A Still Life requires an arrangement of inanimate objects.
This does not seem to meet the definition of the challenge, as a "still life" would have inanimate objects as the subject. It might be possible to have this image of two people walking look less like a snapshot by shooting closer or by cropping to simplify the background (maybe eliminate the verticle pole on the left) and by adjusting brightness a tad. Unfortunately, the water bottle also detracts from the people.
This picture evokes emotion, and tells a story, it doesn't really fit (in my oppinion) with still life. I love how the rain is caught and how the guy doesn't even care that its raining.
