I like the concept. For me, it would have more impact if the person on the left was cropped out completely - just leaving the chairs on either end and the three people. That and little bit lighter sky and I would have scored it higher.
Nice sillhouette here. the people on the far left tat are cut off should be removed from the photo. If you could enhace the orange in the clouds a bit it would really make this image pop. 6
