This is an amazing photo! By choosing the high viewpoint, you've created a dynamic composition. My eye goes immediately to the young man in the foreground, then goes back and forth in a "Z" pattern - young man to older man is one part of the Z. Then the diagonal from older man through standing woman to the seated woman. Finally from seated woman across the other figures on the bench.
And such expressions - the young man is guarded, worried(?) - the older man, passive, pays attention to the woman speaking. The woman speaking is animated, head tilted. The woman seated is serene- fully engaged in her reading or study. The woman seated to her left - one wide eye stares at you, "why are you taking my picture!". The remaining two men... we an only see their body language, not their expressions. So much detail to engage the eye.
I enjoyed this photo of yours very much, as you can see!!!
