Great colors and feeling of speed, but for my taste, the image could stand to be cropped at the top to eliminate the distraction areas. This looks like a lot of fun.
A crisply focused subject with bright primary colours against a speed-blurred and more subdued background - nice. The speed blurring of the wake works particularly well.
I can't make up my mind whether the stuff happening at the top of the photo adds or detracts, though...
