I'm having a tough time trying to decide what the creature is in the water. My first thought is a sea turtle, but they don't have long legs like this creature seems to have. Could be water distortion...hmmm. Other than a turtle, I don't have any other guesses. Okay, onto the voting...I feel that this is a good photo and that it meets the challenge, assuming that what I'm seeing is actually an animal..LOL It is well framed...no wasted space. The subjects are in good position. I like how you were able to capture the water coming off the human. Although maybe just a tad on the bright side and washed out, I like the colors and the glare off the water drops. Good luck in the challenge.
I wish I knew what the animal was in the water - a dolphin? a shark? a turtle? a manatee? Right now all I can be sure there is in this photo is a man wearing goggles.
