An unusual perspective on this species. Nice colours on the head and face. Good composition too. You did well on the blacks but I think there is more detail to be pulled out in the whites. Do you photograph in raw? If so there are a couple of sliders you can try such as the highlights one. Another thing I'd suggest is to boost your ISO for moving subjects...better chance at consistently freezing the action with the resulting higher shutter speed.
Both the Highlights and Shadows sliders are usually the first ones I reach for, and they usually work wonders. Some Exposure tweaking is often in order, too, to bring out the best detail in one or the other. This looks like a good job to me.
I'd bring it into PS and add canvas on the bottom and left and see if content-aware fill could work its usual miracle, then straighten the "horizon" (level the wake). You'll have a very nice image then!
