1) little girl is fine, buuuut the people behind are cropped off awkwardly; SO, watch the backgrounds....a TALL framing on the girls would have made an entirely different type of shot. On grab shots an unposed stuff like this, backgrounds need to be decided upon usually before taking the shot. That means looking behind the subject and seeing what problems there are, then figuring out how to get a clean, simple background. Now, the older woman seated: her skirt has stripes on it, and I wonder if it's sort of flag-inspired, for a welcoming ceremony. Just wondering. The headless men? Not a good background.
2)A posed shot in from of a beautiful, large American flag. A background that MAKES the shot!!!! Their head overlap on the flag is superb!!! A bit too much top space, which caused the hands to be cut off by the bottom of the frame. Takes a 10 and pulls it down to a 7.
3)A little bit of what I call, "too much top space". The 3:2 aspect of modern d-slr cameras makes the frame "very wide, but not very tall" when shooting in horizontal capture mode; this shot needs to have the mens' heads higher up in the frame. Not by a lot, but by a bit. Too much salt, and the eggs are ruined; not enough, and they suck. You know what I mean. Three aces and a pair of kings is a full house...take away one ace and put in a 10 and you have a measly two pair. You seen to have a 4:3 camera, but still, the issues are similar. Gotta see how the "people" fit "the periphery".
My overrall advice is super simple: WATCH the EDGES of the frame like a hawk while shooting the shots. Do an all-over-the-frame eye scan on every single shot, for two weeks. You will move wayyyyy up in results in two weeks.
