Untitled

The front guard seems a little out of focus and some of the background seems to detract from some of the action but this has all the makings of a very good shot. If you maybe increase the ISO and lower the F stop it will tend to reduce the DOF and place more emphasis on a sharper subject. Still a great shot though. Well done.

Just a suggestion

Nice work! Just to continue on Ken's suggestions, I'll add a few thoughts of my own.

1. Maybe try getting closer to fill the frame more with your subject. You could get physically closer, or shoot with a longer lens.

2. In this case I think shooting from a lower angle might have helped, as it could have put the biker up against the sky, and eliminated at least some (if not all) of the distracting background elements. Bright areas attract the eye, so the RVs are the thing to avoid here.

3. If you have a powerful flash, you can try using it during the daytime. It'll make your subject relatively brighter, allowing you to underexpose the background. This will give the sky a cool dark blue look, and will darken all the other background elements too. I've seen flash used for some really cool motorsports and bicycling shots.

Have fun! You can have a blast shooting this kind of fast action subject.
