My first impression was: simple, good deep DOF, no "wow" factor.
The composition is good, the symmetry effect is there for sure. Using a building to display symmetry was a good idea. However, the symmetry in this image is not fully balanced. You could have overcome this in two ways, either moving your shooting position more to the left, or by rotating the canvas a little clockwise in the post processing phase.
The lighting is a little on the dark side, this could have been taken care of by adjusting the levels in post processing or by adjusting the exposure setting one stop on your camera before taking the shot.
The clouds and sky look awesome and give your image a lot of charachter. The longer I look at this photo the more I like it. Good job.
Very nice image. The sky looks very neat for the photo. I think that the object taken is a little too dark though, because it just looks like a triangle. Good job.
