This really is a good shot, nice and crisp, good colours, DOF that kept the background in focus to show the patches of grass. You were a victim of voters not reading the challenge description and making their own mind up on what meets the criteria.
I believe the picture would have been stronger if you would have moved a litle bit to the left when taking the picture, that would have put a white background behind the skier, the patch of gras interferes badly.
