The bottom rail does take attention away from the overall design and leads the eye out of the image. If you crop (yes crop) the image off the top you will get a more graphic style image with zig-zag lines framing the light. However, I do not feel it is strong image to begin with. I shot subjects like this last year and everything had a deep gold cast. It was awful, so I converted some to bw and everything looked better. If the aim is ambiance, the overwhelming lines steal the show.
