I wish you could see this a little closer, but I realize there were probably zoom limitations. I think I would have liked a little more action as well, maybe some water coming off the oar, or more of a pathway where the boat had been... it looks to be moving rather slowly. Good subject though...
exposure tough - bright whites and reallly darks hard to capture - if this picture is about the guy, zoom or crop in - if it's about the water, lower the camera - if it's about the setting, lower your position and raise the camera to get a background
