WoW! Really? I was almost willing to bet it was a reflection of some kind. I think you did very well here and there should be lots of opportunities for something interesting to walk along in front of that should you return.

The angle of view for the center looks a little tough, I guess that's why we were looking at a balcony in the center. At the risk of looking a little silly maybe you could bring a small step stool or step box or something to help elevate your viewpoint and make this thing work to your advantage a little more. Or pre focus and do some blind shots by just holding the camera up and taking your best guess. The point I am trying to make is that the experimental plane for something like this is wide open. Go after it from all angles.

Good Luck!
