I was in the parking lot at the post office, and had just recieved an 18/70 zoom, and wanted to try it out on the old shed blown sideways by hurricane Wilma. The biker came around the corner at the same time, and I instinctively timed the caputre. he was moving about 20 mph, It was just a lucky shot with the right shutter speed to make it look like the draft is sucking the shed over sideways, cartoon style. You never know when the good one is going to happen, you just have to be fortunate, and ready. Not edited.
Not only does it work (how you explained it) but it also works so very well color-wise too: the color of the wind-whipped garage and the biker and the post give big pops of blue which is further accented by the little whisps of blue in the background. Nice job. And enjoyed the story too.
Blur causes the technique of camera panning comes to mind viewing this or a case of visual dyslexia, my initial observation (probably a different cartoon) - was that the shed is moving fast in the opposite direction of the bike.
