This is a very nice shot. I love how you can see each dot on the golf ball. I also love the shadow seen in this image. There are great uses of value in this photograph. I like how you also captured great detail. NIce work.
I assume the focus was set to capture the thin circles of light reflecting from the right edge of the gulf ball. And the consequence of the decision was that the circles facing us would be a bit blurry. This was the right choice, yet I would have liked just a little more sharpness throughout. It also looks like it was a conscious choice to wash out the texture of the ball on the left side. Somehow this choice makes the photo seem a little out of balance - as if the right side should have been cropped more tightly. Still it seems to be a powerful shot.
I think this may have looked a little better if the background on the right wasn't shadowed. I nice pure white would have been great contrast to the shadow on the ball.
