Congratulations on a great take. I\'m very impresed with the stopped motion, and the form of your subject. This has a real sense of movement.
I agree with BakerBug below that something about the picture does look unlevel. I\'m not convinced we can go by the fence in the background (who is to say if it is parallel with the subject). Nonetheless there is somethign about it that makes it look a little as if the horse is racing up hill. Perhaps a slight rotate was in order, but not usign that back fence for alignment.
I would have loved to have seen more detail in the front shadow of the horse and less blow-out on the jersey. I think you could corrcet the first with curves, but I doubt the blow-outs could have been saved (although this depends on if they were lost due to your contrast editing).
I hope my comments help and Good Luck in future Challenges!
Nice and crisp, especially the jockey. A little blur around the horse's hooves, but nothing too major. Nice color, background isn't too distracting. Well done. Good luck in the challenge.
Great capture, but it would be much better if the shot were level. Notice the fence in the far background in the top of the shot. A clock wise rotation with a slight crop would fix this nicely.
