Excellent job capturing the kids shear pleasure.
I agree with eeneryma (real name?) about the hand. Interestingly, it looks like he might be jumping on a fence, or at least alongside. A bit disconcerting without seeing what he will and on/in.
In the first, I love the expression and kinda like the eye of the orca float(?) included. A tighter crop loses the context but makes a nice portrait if you roughly crop out the left half. I might be inclined instead to continue the unusual crop and cut from the top just down to where the pavement touches the float above her head.
