Easy Rider

First off, very well composed. Your eye is instantly drawn to the bicyclist, and then the shadow leads into the water ripples, which really add a sense of motion. The beach jutting in on the left does a good job of balancing the rider out without being too distracting.
I think that black and white works well here, both in terms of adding a feeling to the piece and also for putting a little bit more focus on the great composition. I do feel like there's a bit too much negative space on the top right, but that's more of a personal preference, and not really an issue with the shot as a whole. You might be able to burn the wispy little cloud bits on the top right (set to midtones) to fill the shot in a bit more, unless of course it's intentional, in which case, ignore that <img src="e.deviantart.net/emoticons/w/w…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="453" title="Wink/Razz"/>. All in all, well done! <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="366" title=" (Big Grin)"/>
