C&C per req:
1. An odd crop, but it seems to work. The face seems slightly soft, and the sweater is too hot; blown or nearly blown at the back.
2. I think a reflector image right would have helped, as would a leveling of the image. Not sure what the pink smear on the sweater is, but it wouldn't hurt to clone that out. Again the white is a trifle hot.
3. Cute, but rather too centred. I think a foreground and LH side crop would help, especially to remove the out-of-focus boardwalk and the tips of the leaves in the immediate foreground.
4. A nice family shot, but the faces don't all seem to be sharply focused (A downside to this sort of pose is the DoF required) and the crop is much too tight. You've cropped the gentleman's foot and left buttock, as well as the child's feet.
5. I really think we needed to see the child's hands in this one (it would have helped the others as well) especially. I also think moving them slightly so that they didn't have trees growing out of their heads would have helped.
Overall, they're not a bad set. Watch your exposures and when you discuss clothing choices with clients try and avoid the whites if at all possible.
Just my $00.02 worth - your mileage may vary.
