I know for a fact several guys here would go apoplectic on hearing an utterance of guidance to a picture they have deemed fit to share with the rest of the planet!
So one has to know something about the folk we dare to be honest with. Still, it could very well be that the crop we sought is exactly what the photographer was trying to avoid, distancing themselves from expectations.
But let's imagine that, in this case, we have open-mindedness and a wish to hear feedback. I do think Dave that is what you like.
I agree with Andy that the last picture, with the two joyous kids on the left, is sufficient and we even can sacrifice the girl on the right, (a big step, I admit), but then we lose the guy with the hat and now have a strong focused picture. Amongst the standard aphorisms of photography 101, (most of which I disobey), such as frame close and crop closer, don't have rods/poles coming out of your subjects head, exclude what is not absolutely needed and the like), excluding the distractions is the most important. The picture, unless one is including multiple scenes, such as Pieter Bruehgel the elder, have just ONE center of focus.
With that I would advocate cropping to make each picture stronger. When the folk in the picture are given the control over the visual real estate, one has a better chance of stopping passers by in their tracks and inviting them in to get seduced!
If that is what you want, then crop. If you are documenting who was there, then don't!
