I was not able to vote on this challenge, but if I had, I probably would have given you a 5 or 6.
While I think it is relatively clear on the before and after, I think that simplifying the scene a bit would help with the comparison. I find the aluminum swirls in the background to be distracting as they are fighting for my attention. If you had left a little more negative space on the bottom of the photograph, instead of the top, there would have been lots of beautiful reflectsions in the metal. The aluminum rod and threaded fitting with just the two metal swirls in the foreground would have been nice and simple, and easier to understand.
I hope you find these comments helpful. If you need any clarification on any of my comments, please feel free to pm me. It might take some time for me to get back to you.
