Nice action shot. I know the time of day these events take place at make the lighting a nightmare, especially with a dark horse and white breeches. Not crazy about the darkend edges because it doesn't appear gradual enough particularly on the sides.
I am not a great fan of vignetting so I may be a bit biased but I don't personally think it adds anything extra to what is otherwise a pretty good action shot.
woohoo!! About time someone entered a shot of an eventer! Great form and focus on the part of the rider, and the horse looks like a cross-country machine. 9
The logs in the lower left of the image as well as the yellowish bush are a bit distracting but I like the framing you did around the border. All that being said it's stil a very nice image. Hope this helps.
nice burning around the edges. i think chatching the horse coming over the jump would be a more dramatic photo, but this isn't bad. it just isn't popping out at me is all-5
Maybe a tighter crop on the horse and rider to eliminate the logs on the lower left and the flowers at low center. The shutter speed was perfect though - the splash is nicely frozen. The vignette caught my attention first though instead of the subject(s).
