Yeah, but what kind of helmet the rider chooses for his safety is beyond the photographer's control! LOL It's a race, not a photo shoot.
I like #1 a lot. I probably would have cropped it a little tighter putting the rider on the left side of the shot and allowing the viewer's gaze to follow the trail to him, right to left. (make sense?) Even better yet, when setting up the shot, to put a left-upper focus point on the riders head, but also keeping the trail behind him still in the shot. Then the crop would be easy. My .02 Nice shots.
