Not a bad pic. The composition is decent - strong subject. A level shoreline might have made a stronger impact though (parallel bands of colour behind a subject usually emphasise the subject well). And there is good focus (although you could probably sharpen it up a bit more in pp).
Two things probably hurt your votes - firstly the lack of a more solid connection between your image and the theme. Most people tend to overlook the title...
And secondly, the overall tone is a bit flat. Needed to pump up the contrast and the colours a bit. On this site, photographers usually talk of getting their images to 'pop'. That's a good description of what I mean - if it was more vivid it would burst out at your eyes more.
First let me tell you the things that are good in your photo.... crisp focus.. baby anythings are something ppl like to see...ok, saying that, let's look at the things that could use improvement.... the b/g isn't interesting... not the water, not the sand... for me, the title is the only thing that makes this photo meet the challenge... I gave your shot a 5 and I score high especially wildlife as it is my passion.... this was a difficult challenge and there were a lot of excellent photos that met the challenge... I know it's difficult to score low but... get back on the horse and go for it.. you can improve and in time will value the criticism that will help you stretch beyond your horizons.
