Armand, "Sharpness" has become a shibboleth among modern photographers. It's certainly true that visible camera motion is a problem, but the tiny bit of sharpness you lose because of subject motion or slight mis-focus usually doesn't matter unless you're doing the kind of precise landscape work Chuck Kimmerle does.
The first four are pretty. The picture of the kids is the best of the lot, though it needs a slightly higher gamma and a small reduction in the blue cast (look at the white stripes on the center kid's shirt). Good shooting.
