It's a good idea not to strip out the exif information from your shots. In the child shot, the eyes appear a touch soft. But there's good detail in the part of the hat nearest the camera. The exif data would reveal if the fault was with a wide aperture and poorly chosen focus point, or if it was due to something else. When you're shooting with a wide aperture, you must be careful that the camera chooses the right thing on which to focus.
In both shots, there is clearly a "direction of movement". A center composition, as you have here, will not be as interesting as one where you gave the subject room to move into and cut out the dead space behind them. The rule of thirds is appropriate in this case I think.
I live on Long Island. This looks like a north shore beach. Yes?
