It is an entertaining photo effort with many flaws. My sad effort, with many flaws, was a 30 second touch up as I couldn't be bothered doing much else.
There are several different water patterns in the original picture.
At least the water at the side of the camper is now at the same level as the front of the vehicle. You could clearly see the water level at the CT wheel arch and at the rear was at a much lower level than the front, and a slight tyre wake from behind the CT indication it was moving. As others commented there was no bow wave, yet vastly differerent water levels!
