Interesting, Needs just a little more contrast to make the turtles stand out. Alternatively, I'd like to see a bit of shoreline to add scale, but that might not be possible.
Shades of Dr. Seuss and Yertle the Turtle. Very cute and nicely exposed and composed. Possibly focusing tighter on about half the turtles might have provided better detail on what an individual turtle looks like.
Weird, but it looks like you have some chromatic abberation at the near end of the log. (The magenta halo...) It typically happens when there is a highly varied contrast in the lights and darks on my camera. This doesn't seem to be a situation that would merit the C.A. result. But to counter that effect in P.S. you can turn down the magenta tones.
I give a 6 for a good capture. It can use some color and a different point of view.
Nice, different, but small. I think this picture would be so much better if you took advantage of the maximum size for submission because there is just so much details that your reader could have enjoyed more if it was bigger. But the diagonal arrangement and the beautiful ripples of the water as well as the earthy colors make this a very attractive photograph.
