I like the symmetry of the shapes in this shot. The only problem with the shapes is that it pulls my eyes from one place to another. There seems to be no firm focal point.
The photo itself is a bit on the dark side as well.
Overall, however, I believe this was one of the better shots of the symmetry challenge. It met the challenge and did so with obvious talent.
It's not the most attractive picture but I can tell you spent some time getting everything symetrical. Your cropping and attention to detail is Excellent!
