I think a lot of people are in agreement that trying to get too much into the image can fall short, it's a nice image but it would have worked brilliantly if two things were different.
Firstly the woman pushing the pram - Her leg would ideally not intersect with the man's arm.
Secondly, pulling further out and having a third background subject in the empty space to the right of the couple pushing the pram. This would have given a reason for pulling wider, and shown a coincidence and a balance that would really draw attention. The three subjects framed by the surrounding white beams, plus the two subjects in line with the middle two white beams.
The wider you shoot, the more things that have to perfectly fall into place to make a great image. It hardly ever happens but when it does it's magic. Unless there's a compelling compositional reason to go wide, you're better off coming in close and doing your best with a smaller frame.
But it's no use worrying about elements that were never there that could have made it better - Working with what you have here in front of you, I would perhaps take several steps to the left to frame the main subjects between those white beams and crouch down lower to create a horizon line from the grey asphalt so that at least the head + shoulders of the man and the woman would rise above the horizon line and into that dark frame.
Then it's just a matter of timing for when you click the shutter (other people have passed out of the way / the birds are doing something compelling etc.). Given their positioning, you could end up with a nice diagonal from upper right to lower left, going from the man, to the woman, down to the child, and if you wait a while and the birds move slightly left and the gazes of all three are directed at the birds, you would have a slam dunk diagonal composition.
