Nice 3D sculpting of the main subject here - the limited DOF of tele lenses really makes them stand out. And ditto what jnconradie said: Wonderful background, almost like an antique backdrop painting..
(PS: Something about the reds here tells me you've used the Photoshop "shadows and highlights" tool... am I guessing right?)

Great expression on the rider's face here. And your photo proves that horses do pick up all of their feet at once at some point in their stride :) I am seeing a number of possible challenges for which this could have been intended. Challenge 14: Movement, Challenge 37: Capturing Emotion, Challenge 48: Games and Hobbies, Challenge 86: Sweat, and Challenge 87: Living Colour come to mind. But I'm guessing that the real intent here was Challenge 48: Games and Hobbies. Jim H.
Larry, I just love that blurry background... just enough detail to be sure what it is, just little enough so as not to distract. Well done! Regards jnconradie
