Sand blasts are great photos. IMO you just missed the optimal timing. It would have looked better if you could have caught the ball above the trap with the sand chasing it. Not a bad shot though.
Would have been even better if you waited just a split second more. I shoot golf all the time and the shot you took would have had a little more sand up in the air. Great shot though.
I really like this, but I would have cropped it closer -- more emphasis on the guy and the ball. That upper background of the trees and sky doesn't add much to the picture (IMNSHO).
