Thank you all for your comments.
The focus was indeed on the shadow as it was the main subjext.
The shadow rep the past when the two figures were closer.
I think this was a good idea and really has potential to be a great shot. I love how you kept the shadows as part of the photo. The problems I see are that the main subject doesn't seem in focus, maybe using a higher f-stop would help that. Also the background is very dull. I simple white poster board woould help to add contrast and make it pop a bit more.
