I was not able to vote on this challenge, but if I had, I probably would have given you a 4.
One of the most difficult aspects of this website is submitting a photograph that clearly conveys the theme of the challenge. The reason your photograph did not score well was because the viewers were not able to figure out the "before & after". While you may know what the message is, you have to understand that it is your job as a photographer to get the message across to the viewers. If you browse through the entries that faired a little better, you will see that most of them have 2 distinct aspects to them. This is the main difference between your photo, and the rest.
Good luck with your future challenge entries.
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.
not 100% sure how this is "before and after"- the horizon is quite slanted too. Sorry to say that I don't really understand this photo.
You did however catch a nice blue in the sky with some cloud contrast... if you straighten it up and crop out the bottom... say... half of the photo, you could end up with a decent cityscape.
