Nice shot, really well composed...i'm not sure about the prime object because i'm leaning to look at their hands..still, i think it's a nice shot for this challenge!
Wow! I love when I see an image and get a sense of the people in the shot without seeing their faces. I also really like how the dead leaves are scattered around the sidewalk. One thing I would do to it is either show all of the flowers or none of them at all. It seems cut off and uncomfortable.
