Not sure about the brightness in the upper right, but the rest of it is wonderful. Love the motion, the deep lines, the grain that I can feel and the reflected shadow.
I looked at this for longer than any other photo in the challenge and couldn't figure it out. I could pretend I get it and vote high, but then I'd be kidding myself. I could admit I don't get it and vote low, but that would be mean. So I'm not voting. But well done for expressing yourself.
8 - I like this, creates a strong sense of movement and has a wonderful soft feel with the sets of darker lines at 2 distinct angles over a subtle texture in the background. I like the understatement and elegance of this
