Wow, nice catch!! If I weren't going through all the images in the challenge and commenting I might have missed this. Not a fan of the border here but wow what a catch. The flying sand makes for great texture as well as the rusted pole and horseshoe in the background. Excellent.
A good and different entry into the challenge, the image prodived both aspects of technical and artistic success. The image does have the apperance of being slightly over sharpened on the vertical axis of the stake. An ingenious approach and a good action shot make this a worthy entry into the challenge with top twenty potential.
This is actually a pretty cool action shot. I didn't notice the horseshoe in the background at first glance. I fear for your lens with those flying rocks!
