This is a very cool shot, and I have a lot of respect for you pulling it off. I personally very much like "1st person shots action shots". They are fun to try, but they can be tricky, because you have to watch what you are doing while at the same time trying to get the good shot. I'm guessing you were bicycling one-handed, and mangaged not to run off the road or hit a tree, and you still managed to get a shot, and it's a good shot -- kid looking back (was that chance, or did you ask him to look back...?), visible flowers in the blur (was that luck, or planned?), good composition (though I would crop a bit off the right side so there would be reletively more "space" behind where the kid was looking -- I think that is what Mike was suggesting, too).
So I like the picture on its own, but thinking about how you must have taken it just adds for me. Of course, if you tell me you staged it with a model, and took it from a powered dolly synchronized to the speed of the bike, I take it all back!
