Whilst you have something here compositionally - the strength of the primary curved line moving up and across the frame is well handled - I do think you've left too many people guessing as to what on earth the subject is here; for myself, and especially without any detailed input from you, I'm only guessing at its being a basketball, which of course leads to strange thoughts about indoor rain, generally, and more specifically, up a blind alley. The low-key and high-contrast elements of the shot are wel achieved, though in some areas they've taken things too far, so that, for instance in image top left, we have simply a pattern of white pixels with no real reference to a 'reality' behind them, looking more like you've actually lost control of your editing there than achieving a deliberate effect; 'looking like' - if you were actually trying for that then of course you've succeeded, but I don't see a point to it, especially given the majority of the image.
I'm actually surprised it scored as highly as it did here: the mystery of it, the very dark nature of it, and the fact that the subject is really very simple I would usually expect to bring the score down into the 4 territory, so i think you've done well to achieve what you have with this shot.
Very interesting texture. I find your title distracting. I really love the "low key" nature of the lighting. This is an excellent entry for this challenge.
