So I thought I'd head to the middle of your portfolio to find my first comment. After looking at a dozen I stopped here. The natural pose and expression is what makes this images (like you could pose a toddler...). The sand encrusted leg gives us both a candid and snapshot feel. The subdued selective desat works for me. You caught either some artifact or bad bokeh in the tops of the trees which distracts me slightly. In the end it is a shot, perhaps that means the most to the parents who can see all the personality of the child come out in the slightest facial contortion, but it's still an effort that rises above the simple picture of a kid.
