Interesting photograph, the golden spiral is the most enticing pattern related to the golden ratio. I am not sure if the hand adds or detracts from the shot, in particular the blue cable. I would find it more interesting if the pose of the hand would more explicitly appear like having just thrown the marbles in this magic arc. Also, I personally find the the golden spiral more suggestive when it touches the borders of the frame, so maybe cropping tighter to exclude the hand or use lightpainting to draw a frame around the marbles would have worked better for me.
