I really like the clarity and the presence on the bottom of the photo. I think the people in the background detract from the composition and I would have left a tad more space on the right side too.
I suspect that this is a marmite photo. I am not sure, but the change of POV from looking down (at the bench) at the bottom to looking across (the bench) at the top feels a bit odd.
I like the composition, angle shot, natural lighting and all - but wish the people were either not there at all, or if they have to be there that they were there in their entirety. It bothers me with the heads cut off the parents.
Great find. Nice lines. Looks like a shot I'd try to take but mess up. I personally would have camped out a bit so that family didn't pop into the shot, as I don't think they add much. Either way, I like it. Curious to see where this is, as it looks exactly like my town (or at least like something that would be in my town).
