Hrm, I'm not sure if it is because I dont see a spot to focus on and so my eyes wander or because it's not the same enough to see a repeat pattern. It has an abstract feel to it, the lines are almost diagonal but then there are the lights in the bottom left and the wall in the top left that seem like they could have been better off cropped out of the shot. I'm also not sure about the part of the tree, it just seems to pull out of the abstractness of it. It's an ok shot, just nothing there to really grab me.
There is a hostpital in the Netherlands, in Groningen, that has simular balconies. the picture looks a bit unsharp to me, to much compression? .......6
