I hesitate to make comments since I am obviously not an expert, but here goes: the photo meets the challenge and is in good focus. It is just my opinion that a photo should be able to "stand alone" apart from the challenge (not sure that makes sense, in other words, it should be a good subject even if you don't know what challenge it was entered into). I felt that was where this photo was a little weak -- I couldn't see it having meaning apart from the challenge.
I wish I knew what it was. I will try not to let that bother me with this photo...since it is interesing and part of the challenge was to get an interesting view of things.
im melting my brain trying to figure this one out lol, guess im gonna haveta come back and see your extra details to know what it is... and its hard to comment without knowing what it is but overall it deffinitely is an interesting image :D
